My ovarian cyst has ruptured i now have some bleeding and my hcg levels has dropped 6241 to 1177 can the cyst do this i am 7wks pregnant?

Yes: Given that you are bleeding and that the HCG is dropping, it is likely that you are having a miscarriage. The cyst you had is likely where the egg came from and is now being reabsorbed by your body. Even in a normal pregnancy, after the very early pregnancy, the cyst from where the egg was released does go away.

Maybe: The most concerning thing is the drop in hormone level at 7 weeks of pregnancy. This combined with your bleeding sounds like a miscarriage. A ruptured ovarian cyst could make you bleed inside your pelvis, but the vaginal bleeding is likely coming from inside the uterus. A pelvic exam and ultrasound would be the most helpful in figuring out what is going on.
