Anyone exprienced this or in the same boat as me?!?

I don't know if I'm pregnant yet, but I've been having the same symptoms. Feeling "off" since the date of conception, practically. And everything you mentioned (but I also had light bleeding as well). I took a test today, at 11 dpo and it came back with a faint second line. This could mean nothing or it could mean I'm pregnant and I didn't have enough hCG hormone to get two full lines. But the hormone level doubles each day if you're pregnant, so I am going to take another test on Friday, the day my period is due (hopefully AF won't show up first).
