15dpo cramps, no period, BFN

Hannah

Hey,

Just after a bit of advice really.

I came off the mini pill in December after being on it 6 years (cerazette/feonolla). I didnt have my first period until 14th Jan which lasted 2.5 days.

My next period was 51 days later (3.5 days) and the following 29 days later (3.5 days).

According to my fitbit/glow I should've ovulated on the 19th April. I did some opk tests and I was indeed ovulating and DTD a few times before and after said date.

13dpo and 1 day before my estimated period I did a test and got the faintest of blue lines ?ink spill. Since then i've had period type cramps in my lower tummy and weird pulling pains in my lower sides. I'm now 2 days late and still testing and consistently getting BFN on a variety of different brands. I've had period cramps that are milder and no period, fatigued and headaches. Is this AF just being irregular??
