Didn’t break

So I️ had sex with my girlfriend last week and I️ came in her with a condom on, but it didn’t break and had no tears in it. I️ thrusted about 3 more times after I️ started to cum. There was white on the base of my penis and I️ know that usually means it’s hers but I’m scared not all of it was. She now has stomach cramps and they have lasted for the past 3 days. I️ know cramps are a common sign of periods but I️ thought it would’ve started by now. Is it likely that she could be pregnant or am I️ good?
