This is my 3rd cycle TTC. My period was 4 days late, and heavy when it arrived. I also had terrible cramps. But it only lasted 2 days - which is very unusual. The shortest my period has ever been was 4 days. Is there a possibility I'm pregnant? I was thinking I might take a test in the morning. I don't know if I'm overthinking it or if it's a possibility. I know some women think they're having their periods when they're actually pregnant. Idk. I think I might be crazy. Any input would be appreciated!
