I am a 22 year old female, I`ve had 3 pregnancy two were ectopic (I lost my right fallopian tube)and one was a miscarriage at 16 weeks. Recently, I have been fatigued, vomiting, sore nipples, and having lower abdominal cramps that last all month long, also my periods for the last two months have been little earlier than usual and only lasting two days. I also notice an increase in vaginal fluid( no odor) and my stomach feels live muscle are tightening and releasing around the belly button area. Can this be a pregnancy or maybe ovarian cancer?
