I had one in early pregnancy for 5 weeks I bled bright red more than a period almost every single day. It was increditably frightening but if it makes you feel better I had never heard of one not resolving. I'm now 30 1/2 weeks and everything is going great and she is as healthy as can be! The fact that you are bleeding brown is a good sign as well since that is old blood and not fresh blood. The only thing I can say is try to take it easy and stay off your feet, no sex, and if you start cramping or things get worse call your doctor asap.
I am 7 weeks pregnant and spotting blood and brownish blood for 7 days. I have not been diagnosed with hematoma though. Sorry. I hope all is fine with you!
Has anybody else on here ever had this problem while pregnant?
