Can/will I become pregnant?! :/

So I got my period on Wednesday, it was normal, my period became light by Friday, my partner and I hadn’t seen each other in a few weeks, and we really wanted to have intercourse, we went in the shower and done the deed. He did finish inside, which we have done before once, a while ago also on period and nothing happened(didn’t fall pregnant) but the next day my period had completely stopped. I usually have a 6 day period so I thought this was very unusual, and I fear that I may now become pregnant..
