I feel so defeated

I was diagnosed with stage 4 endometriosis at 20 years old. I lost my left ovary in that process. We did everything like we were suppose to this cycle. We were very consistent in every other day of BDing, I took ovulation tests until they turned positive and took extra steps there. Today I'm 14 DPO and I took a test and low and behold another negative. I'm so sick and tired of seeing negative. I've prayed to God to just help me through this. I'm currently crying right now because I dont know what else to do... 😞 I feel so defeated and I dont know if I'm gonna be lucky enough to be blessed with another child. 😭
