A.M.
I am 21 weeks pregnant and I have had spotting and light bleeding through my entire pregnancy so far. I never had any with my first either. It happens randomly, sometimes it will be a few days since we've had sex. It could be sex or it could just be just because. I freaked out at first, but they do not seem to know why I am bleeding and the baby is just fine every time they check her. Hopefully everything turns out fine, but I know exactly how you feel, good luck!
