November, period lasted over 3 weeks & had large clots. didn't see a period in december, but bleed during/after intercourse (no pain)... what's wrong?

Get checked.: I am always concerned about bleeding with intercourse (unless having a period), because it can be a sign of cervical cancer. That doesn't mean you have it, of course, but it means you should be evaluated. It also sounds like you have heavy bleeding and clots, which may be a sign of other conditions such as fibroids - or even miscarriage! please go in and have an exam. Far too important not to! lg.
