Missed period

Advice please

I was due my period 8 days ago. 8 days ago I had some intense cramps and so I was expecting my period to start… but the cramps went away after a couple of hours and I still haven’t started my period (8 days later)….

My period is extremely regular. On the dot, my cycle is 28-30 days and I’ve not had any changes to this in years.

This is really not normal for me at all - a missed period.

We had sex around the time I was expected to ovulate, but we used a condom, it didn’t break and it was used correctly. I read that it’s 98% effective.

We are not TTC… and I’m a little nervous about testing for pregnancy - I actually think it can’t be possible. The chances are ridiculous.

What do you think? Poll included… (also…do condoms sometimes not work?!)
