False negative or chemical pregnancy? Posted: 04-22-07 06:20am
Doc feels I either had false positive or
had a chemical pregnancy. I believe the
2nd since I had all pregnancy symptoms
(hunger, mild cramping, hot flashes...).
In addition, I had bloodwork done on 4/9
for an unrelated matter and it came back
fine except low iron and the only other
time I had that was when I was pregnant
the 1st time.
I still haven't gotten my period and I
have to go back to doc next week to see if
it's started or to find out why not. I
dont want to take meds for it to happen, I
want it to happen on its own. I've never
been this irregular. How long after a
chemical pregnancy does it take for your
body to have a period?
then to make matters more complicated, we
haven't been using any protection since
our 4/6 digital result showed pregnant.
now i'm getting paranoid thinking I
haven't gotten my period because maybe
after the chemical pregnancy ended & when
my period would've come, we got pregnant
in between there? Is that possible? Thank
you SO much!
"Chemical pregnancy" is a clinical term
used for a very early miscarriage. During
a chemical pregnancy, a pregnancy test
starts off being positive... but soon
after implantation, the embryo dies and it
can't be seen on an ultrasound scan. It is
hard to say what really happened in your
case because you had the ultrasound scan
too late after the positive pregnancy test
on the 6th April. According to your last
period on the 28th of February, a positive
pregnancy test on the 6th of April would
mean that you were 5 weeks and 2 days
pregnant at the time. If you have taken
the ultrasound earlier, you would have
probably seen the gestation sac in the
uterus and the pregnancy would be have
been confirmed. The opposite (no gestation
sac) would suggest a false positive
pregnancy test-result or extrauterine
pregnancy if the test was still positive.
At the time of your ultrasound scan and
another pregnancy test, 11 days later, the
sac could have disappeared and hormonal
levels (HCG) dropped. Now we can only
guess what happened.
It seems that you had a false positive
result because if you had had a chemical
pregnancy, you would have had vaginal
bleeding (period) during the miscarriage;
chemical pregnancies end with vaginal
bleeding. In the case of a so called
"missed abortion", where a dead embryo is
not expelled from the uterus, pregnancy
tests are also negative and there is no
vaginal bleeding... but an ultrasound scan
will detect the dead embryo in the fetus.
So, the only possibility left is false
positive test.
Further, you might be experiencing a
functional ovarian cyst which produces
hormones that delay the menstrual period.
It doesn't seem likely that you are
pregnant right now. To get pregnant you
should first wait until you experience
another menstrual cycle as the present
cycle has not yet finished (no period has
come yet). Nonetheless, you can take a
pregnancy test to assure yourself. And if
you don't get your period soon, you can
consult a gynecologist for more
professional help.
