I think im pregnant but theses pee sticks are coming up negative!

I thought I've had symptoms for a few weeks now. I was supposed to start my period yesterday but I don't even have period symptoms. I was pretty sure I lined up with my ovulation...

If I'm not pregnant then there's something else rearranging my abdomen. I dont know if this is even a pregnancy symptom but it hurts to touch the right ride between my belly button and right hip, my stomach feel hard And I was queezy last night more than usual, this morning I I thought I was going to blow cookies everywhere.

I need some advice, am I just making up the fact that I might be pregnant?
