So for the past week I’ve been waking up feeling very nauseous, lightheaded, tired, and just out of it. I’ve been recently starting to go to the gym everyday with my bf after never really working out, I’ve been eating a decent amount I’d think, and I’ve taken a dozen pregnancy tests that were all negative. I don’t understand why I’m feeling this way, and I get waves of nausea all day long. I don’t know if it’s maybe this Michigan weather changing, or my body getting used to working out, but it’s kind of scaring me.
I haven’t thrown up, it’s just more of a lingering queasy feeling in my stomach.
Someone please help !

Sex April 18th, took 3 Meijer brand early result tests before my period on May 4th, my period ended May 8th. It seemed lighter than usual.
Am I pregnant?
