Last test was taken 17th and got BFN. The last week... Last Monday I started getting sore nipples, sore boobs then followed Thursday! (And becoming more tender) Friday I got 20 minutes of cramping and assumed AF was early but no cramps since. Yesterday and today I have experiences dizzy spells and twinges in my lower abdomen, but not cramps. I really want to test tomorrow but I know SO thinks I should wait 😂 has anyone experienced similar symptoms and when did you test??
