EXTREME Fatigue

Ok so since I had my period 11/12-11/19 I have been so freaking tired like omg . I sometimes get really tired like that on my period but it hasn’t stopped! I’m way past my period and now I’m feeling EXTREMELY tired ! So tired I almost fell asleep making a sandwich lol. Now the tiredness has increased and now I’ve been really nauseous all day but I’m only ovulating?? I’ve never been known to feel like this while ovulation.. I wouldn’t think anything of it if this wasn’t a continuous thing.. cramping a little too with lots of headaches.. some women say they know the moment they conceived and I’m starting to believe it but I don’t want to give my hopes up. But the other night I REALLY felt it . Anyone else felt this way and was preggers?

Me and my fiancé been doing a lot of driving long distance driving last two weekends but this was right before I started my period and the first trip was my last day of my period .
