I had sex 4 days into my period just wondering if I could be pregnant it's been a week and a half and I'm getting sore cramps in my belly and back, could I take a test just now?

First, even if you were pregnant its too early for symptoms to manifest.

You can take a test 2 weeks after you miss your next period.

At this point, there is no signs of pregnancy, you will have to wait to miss a period, and then wait two weeks after, before you test. When is your next period due ?
