I wanna get pregnant. but i've been bleeding n addition to my period. i have been havin unprotected sex wit my boyfriend. wat could it be?

Many causes: The menstrual cycle is under numerous influences, both externally (e.g. Stress, weight changes, diet, etc...) and internally (e.g. Pituitary gland, ovaries, adrenal glands, etc...). Additionally, pathology like uterine fibroids and endometrial polyps can also intervene. Sounds like a thorough work-up is in order. Of course, a pregnancy is always a consideration. Get with your ob/gyn asap.

Many things: If you have a positive pregnancy test, and you continue to bleed, a miscarriage may be occurring. If you never had a positive pregnancy test, and you are bleeding on a regular monthly basis, those are your periods. If you have irregular bleeding in between periods, seek help with you gyn
