Pregnant?

I had sex 22 januari and had my ovulation around 23-26. I'm not sure. I felt some light cramping the last days. I took a preg test 30/1 and the first one had a suuuuper faint line, I took another one after and that one was negative..? AF is around 7-9 februari. What do you guys think? Should I take a test around AF? I wan't sooo bad to be pregnant.
