Looking for some advice please - my period is 2 days late despite it never being late usually. AF was due 15th, had cramps start on the 12th so assumed I was out and waited for AF to show but she never did. Since AF was due I have been having very mild cramping on and off but only for like 20 mins at a time. On the 16th I had a bad headache and felt dizzy then today (17th) I’ve felt nauseous on and off all day. Tested everyday since missed AF but all negative.

I am now 16 DPO (estimated) and 2 days late. Anyone had a BFP later than this or am I out this month? If it’s not pregnancy then I have no idea what’s going on, any help would be really appreciated 👍🏻
