Chemical pregnancy

Hi guys, I just had a chemical pregnancy last week, and I haven’t taken a test in 2 weeks, I woke up today extremely nauseated to the point to where I had to sit down in my kitchen floor, and then diarrhea hit me outta nowhere, and the stomach cramps hurt so bad.

Edit to add, tomorrow my son will be 6 months old, and I haven’t gotten my period back yet. I have bled, but it was way way way painful, and barely anything so I don’t think it’s my period. What could it be?
