Ok so my boyfriend and i had unprotected sex on april 19th. He came inside me about half of.what he released and joked "now its a 50/50"

Well i got what i think may have been my period maybe a day or 2 early on april 25th or 26th. Lasted about 3.5 days. Cramps were much milder than normal. Dissapointed kind of i put pregnancy out of my mind.

Well last week and this week i have been soooo incredibly tired, having vivid dreams, slight headaches on and off and yesterday just the smell of my kids chicken nuggets made.me.so horribly nauseas...

Could i have had heavy inplantaion bleeding and be pregnant right now? Or is my.body just being weird?
