I took this a few days ago when I was 13dpo. The pic is taken during the time window. Now I have had negative (maybe vvvvfls) the past two days on fmu. I was so excited to get this and showed my husband! We were so excited and I was going to confirm the next morning only to get a possible squinter but probably a bfn. Period is due today and she hasn't shown any signs of coming but why did I get something like this then nothing!!
