Trying to conceive

I started my period on the 1st jan and finished on 10th

I had a positive ovulation test on 20th

BD on 21st and 22nd

Wondering when will be my period be due?

It’s every month but irregular cos it lasts from 7-10 days!

I’m 8dpo and I’ve got a cold two weeks after getting over the flu, and I’m so tired and my boobs and nipples are sore and got creamy white discharge
