Is this a sign of pregnancy or is it too early?

I had my period from February 9-15.

I had protected sex on February 17 and 18.

Even though we used protection, he used one of the condoms I think for too long so I’m a bit paranoid.

What I mean is, he wore a condom, we had sex, he didn’t want to cum too fast so we stopped, he became soft again, didn’t change the condom and we had sex again with the same condom.

It’s been almost 2 weeks since we had sex and I’m having period-like cramps even though my next period is not coming until around March 22 (I have irregular periods).

Is this a sign of pregnancy or is it too early to be having signs? Thanks.
