4 days of preseed and not feeling good

Ok I don't do well with warmer weather and right now it's 84 where I'm at. I've also been using pre seed for the first time this week and have used it 4 times and apparently I ovulated during the time I used it. My basal temp today was 97.89 and yesterday was 97.47 which I'm not sure what that means either cause I just started tracking. How I'm feeling is out of it and warm and a bit cranky, I'm sweating for no reason, and I've taken a pregnancy test and it's negative and I've been having headaches and kind sick to my stomach. I'm also hypothyroid so who the fuck knows, I'm just trying to not strip naked and spread eagle on the floor to cool off
