So confused

I’m 25 days late.

My period is not the most reliable, but it’s within a few days of prediction. Never THIS late.

I took a test when the app predicted I would be ending my period, negative. A test at 12 days late, negative. Then a test at 17 days late, negative.

My husband and I like it a little rougher and we had some intense sex the week my period was expected and I spotted once afterward. Usually it kind of starts up my period, but no signs since.

I don’t get why it’s not coming or why I’m having negative tests if I’m pregnant?

I am exhausted. I never nap, but I’m constantly napping recently. I’ve had a few migraine days and headache days too.
