Im almost ready to give up.

Ive been TTC for a very long time. Right now i’m kinda excited but at the same time I don’t want to get my hopes up. I’m 8 days before AF comes to visit but I’m having cramps and pains in my lower back and sometimes on the right side. My bones have been hurting especially my knees and pelvic area. And most of the time Ive woken up with extreme nausea but no actual vomiting. I don’t want to get too excited though. Has anyone experienced this before? (And its not PMS my pms symptoms comes with wayy less pain and bloating.)
