TTC newbie

Hi.

I’ve had sex on my 2nd ovulation day which was Jan 7th and my predicted Period was to come for the 24th missed that, I’ve had cramping all that week and nausea as well. But it wasn’t my full 28 days until the 28th yesterday. Today my time is now the 29th and still no cycle. I’m going to take a test tomorrow. It has been 3 weeks since the 7th. What do y’all think?
