I'm sorry you're having these confusing symptoms and that you have no one to talk to. There are a lot of reasons for bleeding, and some of it can occur during pregnancy. Sometimes it means something, sometimes it doesn't.
Do you have a doctor? You can see either your primary care physician or a gynecologist for this. If you don't have one, is there a Planned Parenthood near you? If you can't find one, call the national Planned Parenthood number (1-800-230-PLAN) for the name of a reputable clinic near you. Do not be confused by similar sounding names on websites or on clinic doors (things like "problem pregnancy" or "unplanned pregnancy") - many of them have a political agenda and don't even have doctors on staff. You want objective medical advice from a physician (MD), a physician assistant (PA) or a nurse practitioner (NP).
Make some notes now about key dates: last regular period, when bleeding started, when you had sexual activity (even if it was in the month before your last regular period). Have that paper with you when you're on the phone or in the office.
Make the call now and get some advice. Good luck.
