Sore Nipples

Soo I’ve only this month started to track my sexual activity but been off the pill prior for about 1m I had tested last month as only had 2 day period and other reasons for this - today I have had tender nipples I’m not due on my Period till around 25th - would you say it’s to soon to test or wait for my period to see if I miss it

Sorry I don’t wanna not know and do something that could harm the baby & all new too this as a hopeful soon to be parent 🙈
