Spotting every month?

So I've had 3 bouts of spotting since I became pregnant- at 6 weeks, 8.5 weeks and 13 weeks. The 6 week episode was dropping progesterone, so I went on crinone. The 8.5 week spotting was blamed on a tiny SCH and no cause was found for 13 weeks.

It just occurred to me that the last 2 episodes were about the exact time I would have expected my period.

Has anyone had cyclic spotting/bleeding during pregnancy? I know I sound insane, but I really have a gut feeling it's going to keep happening and I've been off the crinone for a few weeks now.

TIA!

Re: Spotting every month?

I have had several bouts of spotting this pregnancy. It mostly went way in the second trimester but came back in the third which caused so much stress and worry for seemingly nothing. No one can find a reason why it's happening and baby looks perfectly fine. I on the other hand probably have a few gray hairs over it all.
