10 DPO and I'm out...AGAIN

Suez

Tested this morning at 10 DPO, not even the faintest line. I took supplements this month and vitex, I got myself checked with scans and bloodtest, no cysts, no PCOS, hormones normal. TTC for a year now and have never had a positive. What is wrong??? This is really exhausting and I don't think I will ever see a positive in my life. Doesn't help that I'm 38 soon.
