morning every day?

2. Mandy asks…
I had sex day before before ovulation test detected positive LH
surge could I be pregnant?
I had sex on the wednesday morning and detected the LH surge on the thrusday afternoon. My
partner went away and we did not have sex for 72 hours. I understand that it is best to have sex
with 48 hours after a positive test detects an LH surge. However, I have read that sperm can
survive up to five days in the womb and am confused as to my chances of falling pregnant. My
period is due next week.
How hopeful can I be??? What are my chances of falling pregnant???
HELP!

3. So ovulation prediction kits detect your LH Surge, which happens
12-36 hrs before ovulation…?
What happens during ovulation, will a test show the 2 lines or none at this time?
Pregnancy Advisor’s answers:
Most likely it will show a neg result. LH surges right before ovulation and then quickly goes back
down. So typically, by the time the egg is actually being released the LH is low and won’t
register a positive on a test.
Linda asks…
Had sex 18 hours before detecting the LH surge – will it be a boy
or a girl?
Just found out I’m pregnant with third baby. As I already have two boys, I have been trying to
follow the Shettles method to have a girl. I have been using the Clearblue Fertility Monitor to
track my cycle. I normally have 3 HIGH fertility days followed by 2 PEAK days. I had sex on my
second day of HIGH. The next morning the Fertility Monitor still said HIGH. However, I took a
separate Ovulation Predictor Test at 2.30 pm on second day of High and it had detected the
LH surge. Therefore, I had sex about 18 hours prior to picking up the surge. Ovulation then
comes about 24 hrs later.

4. Of course I am happy to be pregnant, and want a healthy baby above all else, but just
wondered if you think it’s more likely to be a girl.
The Shettles method suggests having sex 2-3 days before ovulation for a girl, and within 24
hours prior to ovulation for a boy (the day before and also on the day of ovulation).
Thanks!
The reasoning to have sex BEFORE ovulation for a girl, is that the male sperm swim faster but
die off quicker (so they should have died off by the time you ovulate when the egg comes). THe
female sperm swim slower, but live longer. Therefore to get a girl, the female sperm will be alive
longer to fertilise the egg.
I KNOW it’s the sperm that decides the sex of the child, but the timing of intercourse in relation
to ovulation also plays a part as male sperm swim faster to get to the egg but don’t live as long
as female sperm. So if you have sex when you ovulate, the male sperm should get to the egg
before the female sperm as they are slower, but live longer. That is why it’s recommended to
have sex BEFORE ovulation to conceive a girl, as by then , the male sperm should have died
off.
The Shettles method is supposed to raise your chances to 75%. It would be 50/50 otherwise.
THANKS

If it is all true with what you said

5. Can anyone tell me the symptoms before LH surge?
Is there any kind of cramping at lower abdominal side before LH surge? My last cycle was 28
days and therefore I got LH surge after 14 days . Last month I got period on 16th then I got LH
surge on 29-30th day. I don’t know why but in this month my period started on 8th so what will
be mine LH surge date or ovulation day? I am under stress and I don’t want to miss
my ovulation day, now my cervical mucus is whitish in color not exactly transparent . But I have
cramping at lower abdominal side. Have I miss my LH surge or I shloud still wait to check LH
surge?
Please tell me the symptoms before LH surge .Thank you.
I have already checked my OPK test, test line is lighter than control line.
I have started testing my LH surge from 2nd day after my period finished.
Pregnancy Advisor’s answers:
I’m monitoring my cycles at the moment, this month the ov cramps started 4 days before I got
my LH surge.
These are my symptoms leading up to before I get my surge:
4 days before – mild cramps
3 days before – mild cramps
2 days before – Dull ache on one side in the pelvic area, clumsy, low back pain on one side,
1 day before – mild cramps
Day of LH surge – stretchy egg white cervical mucus (ewcm) quite painful ovulation cramps on
one side, like a burning pain, bloated, tired,
Day of ovulation (day after surge) – very painful ov cramps on one side that last a few hours,
low back pain, ewcm, mouth ulcer, tender and bloated tummy, shooting pains down below, tired
I always know when I have ovulated because I do experience the very painful cramps but not
everyone gets it like that and the day after ov I always get a migraine. It’s hard to say when you
will ov as the first half of a woman’s cycle can vary due to all different factors – illness,stress etc
but the luteal phase (time from ov to period) will nearly always be the same length, mine is
always 12 days. Therefore predicting ovulation in irregular cycles is quite impossible without
using opks.
I don’t think you’ve missed it yet as you’ve been testing from day 2 although it is possible to
miss your surge if you are not testing at the right time of day. I always find it best to test around
5/7

6. 6pm. You can miss your surge if you test in the morning. I would keep testing.
Sandy asks…
can i get pregnant 1 day before detecting LH surge?
Me and BF are trying to conceive baby #1 after a m/c in December. I bought the clear blue
ovulation kit and got a smiley face today 4/12… we baby danced 4/10 and 4/11 but we weren’t
able to today but will tomorrow! Has anyone out there got pregnant a few days before
ovulation?
Im so worried since m/c I over evaluate everything!
Ovulation due on 4/13
Pregnancy Advisor’s answers:
Sperm does like for 72 hours but you should really baby dance the whole 5 days because your
chances are wayy higher. On the other hand, if its going to happen it will happen. I know how
you feel i micarried dec 07?, just relax and enjoy!
