Okay, I have irregular periods, always have. I also have ovarian cysts. But, I've seen, read and heard a blood test can be taken to early into a pregnancy. The past couple weeks my boobs have itched like crazy, my lower belly is hard as a rock, I'm very constipated ( I've never been constipated in my life ), my boyfriends been eating weird stuff & feeling sick, and I've had spotting for two weeks now. it's not like a period it's just like faint but it's there. I go to the doctor Monday but could I be pregnant?
