period during pregnancy?

[Ms.RN]

one of my co-worker told me that when somebody she knew was pregnant she had period every month during her entire pregnancy. is that possible? i've never been pregnant and i just know what i've learned in school and i havent heard such a thing.

It IS possible, although rare. I have met quite a few women who experienced monthly bleeding like a period throughout their pregnancies. I suppose ANYthing is possible.

I am pregnant and have a bicornuate uterus, which is basically almost two complete uteruses. I am pregnant in the left "horn," and have my period every month out of the right horn. If I were to also become pregnant in my right horn, then my periods would stop completely. It's a good thing I don't become pregnant in the other horn, however, as then my right horn baby would be five months younger than my left horn baby and would not survive the birthing process of the left horn baby.

My my periods are different from how they've been my whole life because I'm pregnant, however. I used to have a full seven day period with severe cramps at the beginning for the first day. My periods since I've been pregnant have averaged 3-4 days, sometimes 2-3 days, and have been much lighter - half the amount of blood. Also, they have been "clottier," having more blood clots. This is because of the change in my hormones. I know this because the only time I had clots during periods in the past is when I was on birth control.

Women with bicornuate uteruses deal with misdiagnosed pregnancies due to hormonal differences: The body produces the hormones to continue to have a period in the not pregnant horn and at the same time produces hormones to support the pregnant side. If the timing isn't just right, a urine or blood hormone pregnancy test may come up not pregnant when the woman actually is.

Also, because the uterus is shaped oddly and may situate inside the body with a tilt or twist, it may be difficult to see the fetal pole inside the egg sack, or any egg sack at all early on in the pregnancy. It may take many months for the uterus with baby inside to protrude out of the pelvis before it can be seen via ultrasound. At this point, a transabdominal ultrasound is necessary.

For clearest diagnosis, an MRI is 93% accurate.

Wrong. Look up bicornuate uterus or read my post below. I am pregnant and have periods every month out the other half of my uterus.

It's a yolk sac, not an egg sac. Egg sac makes me think of Charlotte's Web.

It's great to hit the "quote" button when you respond to someone, that way we can all know who you are responding to.

Good luck in your pregnancy.

Generally, before 10 weeks or so, U/S is done translady partslly, and an IUP can be visualized well before it protrudes out of the pelvis.

Wrong... it IS possible! I had mine the 1st 3 months of my 1st pregnancy delivered June 15th with due date of June 17th, 6.5lbs 19in & 9.5 on apgar scale, 10 years later I'm 15wks & still having a FULL period!
