Has anyone ever had a negative frer at 12 dpo and still ended up pregnant?

I just don’t understand why I’m not pregnant. We had sex every day during my fertile window (and regularly throughout the rest of the month). I used OPKs. Temped. My cycles are totally regular.

There is nothing wrong with either of us. We’re both healthy and “able” according to doctors. We got pregnant once...a year ago. I had a mmc, but I mean i was able to get pregnant. No luck since then and I just don’t understand.

I’m devastated. I want it so badly. I babysat for 15 years of my life before becoming a nurse. I love children. I have so much love and caring to give. I have a good job. I’ve saved money for a baby. Good marriage. I exercise. I eat healthy. I want this so badly. The timing is just so right. I can’t even look at other people’s children because it just brings me so much emotional pain. Why don’t I deserve to be a mother?

I guess I’m just venting. I know that if I were pregnant I would have had a positive test by now.
