I need help.

Backache, bodyache, tired, headache, craving, gas, diarrhea, vomiting. My nipples having this weird feeling but when I touch my nipples, it's not sensitive just a weird feeling of it. 😕 I'm somewhat moody, well to Glow it's says I'm 15 dpo and I haven't seen any of positive opk. I took a pregnancy test on September 17 and it came back negative. It was to early to take the pregnancy test. I felt like this when I was pregnant last year but I'm not even sure. My temp this morning was 97.00 yesterday was 95.52. I have a deep feeling I didn't O. Ughhhh where is my AF so I can do this all over again. #SoDown😢😢
