Pregnant? Not pregnant??

So I’ve been going out with a guy for about a month now. We were good friends before we started dating and have a lot of similar interests, and I think we could do very well in the long run.

We have sex a lot and started dating right before my state locked down. Now the problem is, is that I’ve taken a plan b when I didn’t think the first protection we used worked, and now my period is 24 days late. We took three different pregnancy tests when I was around 2 weeks late and all of them came back negative. But now I’m pushing into week 4, still no sign of a period at all. Should I take another test??

On another note, I took two of the first three tests with him, and we were both relieved that it came back negative. Should I let him know I want to take another test? He isn’t ready for kids and doesn’t even know if he wants them, and my roommate make a point that if I keep pulling him back in with this baby issue he might start to think I’m trying to trap him or something, or that it might scare him off. Any advice?
