Backpain

A
I'm currently 8 dpo I'm trying not to symptom spot or go crazy this month. We are on our 3rd cycle of ttc and just got married a couple weeks ago so I'm just trying to enjoy our marriage. Now the problem is thou is since 6 dpo I've had horrible aweful lower back pain like miserable back pain. It radiates into my uterus which then aches and feels pressured. I've never had this bad of pain in this area before. Is this something to be concerned about? Could I be pregnant? Should I see a Dr or a chiropractor? Any advice would be greatly appreciated. Thanks in advance.
