Confused !! Please help me

Teshena

Hi ladies my husband and I have been ttc for 4 years now and it has been very emotional for us every month.

I had my af on April 22–26

Glow says I’m ovulated on May 3

I had small amounts of spotting on May 16 (light red)

May 17 it was medium spotting (wasn’t enough to fill a panty liner and it was light red

May 18 nothing

I’ve taken pregnancy tests on

May 19,20,22 (cheapies-negative)

May 24 (first response-negative)

As of today glow says I’m 10 days late.. may16-may 18 I logged spotting

My cycle is usually every 24-26 days

Please help!!!
