15 dpo, AF late 1 day, BFN!

Hello Ladies,

We have been actively TTC (trying to conceive) for over 2 years now. 3 chemical pregs. We have a 4 year old DS.

Today is my 15dpo, no AF(i have a 28 day cycle), AF (Aunt Flo - menstruation/period) never late but still BFN. I had a quinter earlier but when i retested 3 hours later it was BFN.

I also have some really bad headaches, nausea but no vomiting.

I guess im just going crazy and impatient and want to see if there are ladies who are on the same boat as me.
