Bleeding after exercise?
The placenta is actually developed enough at 7 weeks to cause some bleeding. According to a miscarriage support website:
"Sometimes a small amount of blood is lost when the placenta matures at about 7 weeks and takes over the progesterone production. This can be frightening but is quite common and in most cases your pregnancy will continue as normal without harming the baby at all."
Hopefully this is what you were experiencing! Try not to stress, and keep us posted.
Same thing happened to me last October. Went hard during exercise and miscarried a chromasomally normal, healthy fetus @ 14 weeks. I always bleed after heavy exercise so I didn't think it was a big deal. Because of my extensive OB/ pregnancy history ( I've had two second trimester miscarriages, one pre-term live birth 5 weeks early, and a near- fatal post partum hemmohorage) my doctor did a re-occuring pregnancy loss work up which showed that my anticardiolipin IgG was elevated.This antibody causes a blood disorder called APS or antiphospholipid antibody syndrome which has directly contributed to my complicated OB history. Both miscarriages could have been averted by using a blood thinner throughout the pregnancy.
If your insurance will cover it, ask your OB for these test: anticardiolipin, antinuclear antibodies, chromosome (blood, MTHFR), and lupus anticoagulant. These are test for antibodies that may interfere with fetal growth, cause blood clots, stillbirths or miscarriages. (Your doctor probably won't even offer you these test until you have (3) 1st trimester miscarriages or (2) 2nd trimester miscarriages). Doesn't hurt to ask.
Thing is, the OB I was seeing at the time of my last miscarriage knew my OB history, was the "high-risk" pregnancy doc at the practice, but didn't even offer APS as a possibility. I had to go www.justanswer.com and ask an OB there, print out the tread and take it to my new OB who found the problem.
This is why it's called a medical 'practice'?
Blessing to all of you who have loved and lost. My prayers are with you and your families.
