4 days late, spotting, negative tests, HELP!

I started spotting a week before my expected period. It was reaaally really small amount of blood, visible only in the toilet or only on first wipe (light pinkish). That lasted for a week. Then 2 days nothing, then in the evening i had a little bit more blood come out and i thought that my period started, but nothing after that. Whole time i have mild cramps that i usually have a day or two before (“hey im coming” type of cramps”. Usually i bleed a lot and cramp like hell.

I did 5 pregnancy tests so far. All of them were negative (some taken 2 days before expected period date, some a day or two after and one this morning) except one that didnt get control window line but was still “negative”.

I had sex during my fertile days (pull out method, stupid, i know)…

I never had spotting before, nothing similar ever happened and im sooooo scared.

Has anyone gone through anything similar??? Help!

Edit: today is cycle day 34. Usually my cycle lasts 29-30 days.
