Might be pregnant

Melanie

So yesterday was my ovulation day. We had sex early that afternoon. I ended up feeling like I should be getting My period when I know it’s super early . I ended up going to bed at like 2:00 am last night . I didn’t wake up till 10:30 today . Then at 12:30 I took a nap because I was super tired . Since 12:30 ive taken 4 other naps . Ive never been this tired in my life . Could this be a early sign of pregnancy or implantation?
