I’m very confused! Opinions please!

Hey guys,

I’m having a very confusing cycle this month. The past 4 months I’ve been very regular and had my AF at the time the app predicts.

This month I’m 2 days late but had 2 days of brown discharge and spotting which has stopped. Af has not arrived yet either. I’ve tested for last 4 days and all 4 tests negative.

Has anyone had anything similar? I’m also very gassy 😬

According to the app I’m 14 dpo but is there a chance this is implantation?

Shall I test again in a few days?

Thanks for any input!
