Help?¿

I have a pinching feeling below my belly button that won’t go away(been going on since about 3dpo, so I’m assuming pinched nerve of some sort). It’s not deep into my abdomen. I also feel extremely sore on the left side of my back and I have some mild cramping. I’m 7dpo. Mild nausea that comes and goes, but other than that there’s no PMS, no anything. Breasts don’t hurt, I’m not bloated, no irritability, as a matter of fact I’m extremely horny and overly cuddly and loving. (Sorry if a bit TMI). I’m trying not to symptom spot, but I feel sick and great at the same time. Could it be anything, or should I wait a few days? Period is due in 6.
