Yes, me, I had it with my twins and everything turned out just fine. I avoided any heavy lifting and basically took extra care and rests, it resolved itself around twenty or so weeks. Try not to worry...I know it's hard not to...but most times it just goes away.

I also had one and everything turned out okay. It was incredibly unnerving to bleed like that while pregnant but I had an excellent doctor who was always willing to see me. I hope it's the same case for you. I did take it very easy but that was for my own peace of mind, not really doctor's orders.
