Shark week and baby?

Ya
So I started my period on Monday, it was light as it always starts off every month. This month I experienced symptoms as nausea and dizziness. Yesterday I got really ill with a fever of 101, chills and body aches which only lasted that day. Weird, huh? I usually get horrible cramps during AF but none this month which is odd. Last night I had two dreams about my ex who raped me, that we got back together and had a family. Many people have told me you can still have AF during the first three months of pregnancy or having dreams about exes can happen to pregnant woman. Idk what to think about this. My co-workers think I might have a bun in the oven. I don't think so but I finished shark week today.
