No period and BFN!!!

Hi

My hubby and I have been TTC for 3 months

I am very regular on a 27 day cycle without fail!

I have no (zero) symptoms of my usual PMS of headaches, nausea, extreme acute abdo pain and back pain, engorging and tender breast!!

This cycle I am currently 1 week and 3 days late!!!

I have spent a lot on pregnancy tests this month and all I am getting is BFN!!!!!!

I’m getting random lower abdo pains and i begin to think “is this my period!?” But nope!! It doesn’t show!!

Had anyone else had this experience and found out they were pregnant 🤰 or have I missed my period for the first time in 21 years??
