What is going on?

Riley • Army Wife 💛 🇺🇸 TTC Rainbow baby ❤
I am on cd 53, my last period was September 16th. My period is irregular but never this irregular. I have been tired, dizzy, bloated, having backaches, headaches, nausea, food cravings and cramps. My husband and I have ttc for over a year now. I have taken 2 hpt but both negative. Any ideas? Please give any opinions you have!
