When I usually have a period I'm on for 7 days and really heavy but this month I was on for 4 days and really light is there a possibility I could be pregnant. But I haven't had sex for over a month if you read my other questions you will see wh, but some people still have periods when pregnant.

I highly doubt it, if it has been a month... have you been throwing up a lot lately?

If you had a period of any length it is highly doubtful that you are pregnant. Yes, some women do have periods during the first trimester, but it is not as common as one would believe.

Throwing up? Well, this is a common pregnancy symptom, but not all women have symptoms. Every woman is different as is every pregnancy.

There's always a possibility of that if you have not gotten your tubes tied but I experienced the same thing and it was just stress making my body act in that way. I think you'll be fine. I used to freak myself out too until I got my tubes tied.
