Am I Going Mad?? Please some advice

It’s day 32 of my cycle

I’m usually 28-30 days

I’ve been having mild period type pains for 2-3 days now and mild back pain. But no period.

I keep going to the toilet to wipe, expecting blood and nothing. Not even pink. I don’t want to do a test as I’m too scared to see a negative. But it feels like when your about to start but just hasn’t happened.

Even had sex last night and expected to see some sort of blood. Nothing. Please has anyone had this cramps and feelings and ended up being pregnant.
