Feeling like a failure

So I had brown discharge and spotting at 5dpo and then again at 11dpo, and I actually thought just maybe, I was finally pregnant after ttc for 14 months but just this evening I started bleeding right on cue when I was meant to get my period 😭

My cycles are 28/29 days, I ovulate on day 15/16 and most months I get ewcm and clear signs I have ovulated. I just don't understand why I'm not getting pregnant.

I've been speaking to a fertility nurse (as its been over a year of trying) and my partner and I are now both taking a fertility supplement to improve egg quality and his speem. (been taking it for a month and a half now) We've both been eating healthier, exercising 3/4 times a week even though our BMI is in good range 21 and 24.7.

I just feel broken like I'm failing at being a woman, all I want is to be a mummy to have my baby in my arms and it hurts so much trying and getting nowhere.

My partner and I want this so much our own little family, it just hurts going through this depression and pain every month.
