Seriously need help.

So me and my boyfriend messed around at news years but didn't have sex we are both virgins. But he did cum after oral and he fingered me a little while after that just around my clit and I'm afraid he had sperm on his hands when he did. He said he didn't but I'm not sure. I was on my period at the time too and am not anymore. I've been experiencing stomach cramping and bloating. But I am around the time of ovulation. Just weird feelings in my stomach. Could I be pregnant? Please please help. Can't have a baby at this time in my life..
