Could I be pregnant?

The last time I had sex was a little over two weeks ago. Last week, I had a normal period with heavy blood flow and no spotting- so a normal period. My period ended two days ago but I’m cramping still. I read that cramping can be a side effect of pregnancy. Could I be pregnant even tho I just had a normal period and haven’t had sex for two weeks? No hate, just help please.

Additional info: my period was late four days, I took a pregnancy test the first late day and it was negative.

I have no underlying medical conditions that I know of.
