Am I pregnant?

2 weeks ago I lost my virginity and it was with unprotected sex (while I was on my period) . I let my boyfriend convince me to without being educated on it. He didn’t cum inside of me but this past week I’ve been having cramps and a bit nauseous but I haven’t thrown up. I know the possibility of precum (and I know it only takes one sperm) is there but I’m scared to wait til my period is supposed to come. I’m planning on taking a test soon but I’m not ready to have a baby, and I doubt I can afford an abortion pill.
