THICK CREAMY WHITE DISCHARGE?? Am I Pregnant?!?

My boyfriend & I had sex on the 21&22 of April . He inserted semen inside me with his fingers then let some out inside me. I was suppose to get my period on May 2nd. We had sex again may 2nd which made blood come down it was brown n red but it wasn’t a lot compared to my regular cycle. It lasted the 5 days but it was light and no pain which wasn’t normal and I usually get signs that my period was coming I had no sign which is weird. I took 2 test but it came negative Idk if it was to early. 5 days after my period I got brown discharge 2-3days , and now I get a lot of thick white creamy discharge ( no itch or scent etc , lower back pain , headaches sometimes, off & on cramping , Itchy nipple I squeezed it and white substance came out a big appetite and really tired sometimes. Lastly frequent urination with slight sensation after urinating no burning . What’s going on did any of you experience this? Am I pregnant?

& my period suppose to come in 6 Days
