All the signs of implantation and still bfn!!!

[cbttc]

Agggghhhh I'm going insane!!!!!!
I think I ovulated on either Sunday 10th aug or Monday 11th and have a 28 day ish cycle (its varied over the years but of late it's been about 28 days. On Tuesday (3days ago) I wiped and there was a tiny spec of gooey brown. There was nothing on my liner and hardly anything else that day, I also had af cramps so thought it might be coming early. The next day same again, but a bit more and darker brown, and a tiny bit on my liner, yesterday a bit more but again very slight, and all time with the cramps! I've also not been sleeping well and been awake for at least 2-3 hours every night and am absolutely shattered and yesterday I had such bad indigestion and burping all day!!!!! (Classy!!!)
I have gone crazy with poas! Done one every day since wednesday including this morning and all bfn!!!!!!! I now it's quite early but they are meant to be the sensitive ones!!!!

Feeling frustrated!!!! Anyone in the same boat?

How frustrating cbttc but it's still early. From what I've read, I think the sensitive tests are really accurate in detecting hgc once it's in your urine, but depending on your body and you levels of hgc production, if there's not enough in your urine yet then no test can detect it! Also maybe implantation took longer than you thought. I'm on CD 33 now (1-2 days late for AF) and have no AF and BFN! I think it's just a waiting game. Hopefully you just have a shy bean!
