Bleeding with pregnancy

When I found out I was pregnant ( i had been having sharp pain on my right side). Once I found out I decided to go to ER to make sure it was not ectopic. It was NOT but I do have a cyst on my right ovary, that's why I had pain. Well Saturday I started cramping and gushed blood. It didn't stop so often a few hours I went to ER. The did a quick scan ( less than 30 seconds) just to make sure baby was inside. Never checked my cyst to see if ruptured. Then did HCG level ( was 30,000) which is normal as I am 7 weeks along. The only thing was my cervix was open slightly, and the bleeding. They said I'm at a slight risk for miscarriage of it gets worst, which it hasn't. Bleeding has calmed down but not completely stopped. Has anyone else had bleeding with pregnancy??? Did everything turn out ok?? FYI I also have a UTi
