Is this all in my head?

Okay.. I’m probably crazy but I blame anxiety.

My boyfriend and I had protected sex 3 weeks ago. I’m on the pill and we used a condom, I took my pills a little later than usual around this time due to stress and forgetting right away.

Anyway the condom didn’t break.

But it did roll slightly. My withdrawal bleed did come on time but it was a little heavier/longer than usual. ( stress related??) anyway I’ve just been freaking out over being pregnant I’ve taken a few tests. A First response a few days ago, saw nothing with the naked eye, then saw a possible something after inspecting it and actually took it apart( I know you shouldn’t do that) then at 22-24 days after sex I held my urine all day and tested at night and got negatives. This morning 25 days after sex I used two digital s and both said no. Someone I went to high school with posted online saying she had a dream that she always has when someone she knows is pregnant. So now I’m LOSIN it. Is this just coincidence and my anxiety? Or should I still

Be spending money on tests?! Help me I know I sound crazy.
