Im not an expert at this whole pregnancy thing, but ive read sum articles, inthe internet mostly, and there was sumthing that stayed on my mind, cuz a lot of teenagers think that u can still have ur period when ur pregnant, and what it said in this particular article was: "periods and pregnancy obviously dont go together" from my personal opinion I think thats true, u might have light spotting, but not like periods.. Supposely u dont get ur period when ur pregnant, cuz that egg that is released from ur body through ur period, is supposed to be the egg (with a sperm) forming into a baby..So.. I think that its not possible for u to be pregnant if u have ur normal period..
Hope my comment helped.. :?
