Could i still be pregnant if i'm getting my periods?

No, not at that time: A woman cannot get her normal regular period and be pregnant at the same time. However, she can get pregnant a week or two after her normal period. If she has some spotting or light bleeding that doesn't look like her normal regular period, she can check a urine pregnancy test about 3 weeks after sex (when conception might have happened) to see if she is pregnant.

Poss. but doubtful: You can sometimes have scant menses during first few months of pregnancy or if you had some kind of ectopic pregnancy but this is unusual. Do a home pregnancy test which are very accurate. If still with questions then see your doctor.
