Maybe pregnant??

Okay so I think I'm pregnant. Last week I was ssooo tired still am I sleep 5 to 8 hours and then sleep the night dragging myself out of bed.  All of my other symptoms I can explain away but not this I was sure I was pregnant this month. And we were going to wait 2 months so we wouldnt have a baby around xmas and also get the infertility testing done. I have this feeling that I am pregnant and it's a resolved yes I am pregnant no super crazy I am, but this feels right. Today I have spotting 10 dpo and 26 dpo af usually comes on 31 cd. I ovulated 4 days earlier this month. Still feel pretty positive that I am and hoping its just implantation bleeding, but still worried.
