Feeling so down

My husband and I haven’t been trying very long but like many women just “knew” it would happen right away. Of course it hasn’t and I know everyone says it takes time. Last month I had all these weird symptoms, twinges, light cramping, nerve pain. I’ve never had these before and just felt like I was pregnant. Then AF came and I cried. I’m 8dpo and I feel nothing. I haven’t had any cramping so I’m just in a mood where I feel like “welp didn’t implant. Not pregnant again. I have no symptoms yet another fail”. I don’t even have any desire to test where before I’m antsy. Just feeling super blah
