Hi I had sex dec 18th ended my period dec 15th and haven't felt well since I had my period but a very light one is it possible I am pregnant

If you had sex, protected or unprotected yes, it's possible.

Even though I had my period a very light one but was one

The sex was unprotected

I understood that - but a light period can be spotting while pregnant. Any time you have sex you risk pregnancy. It's as simple as that.

Do you mind sharing how old you are? Are you trying to become pregnant or are you stressed at the idea?

While pregnancy is one possibility there are others including stress and other illnesses. If you haven't been feeling well since the end of your period which predates your having sex, there is a chance you are sick and stressing yourself out.

You can try to calm down and wait and see if you miss your next period. Then take a home pregnancy test (HPT).

You can try a HPT though it could be too early to get an accurate reading.

Or you can go to the doctor and make certain you aren't suffering from another illness/disease. They may also do a pregnancy test.

I'm 21 and no I not stressing if I sm pregnant I am fine with it.. . It was jusr a curious question.. . Thanks for the help
