Sore gums, metallic taste and back cramps

Katie • 33 years old 💙 + baby due in October

I’m only 7dpo with AF due on 2/22 so I’m worried it’s too early for real symptoms? I’ve have had back cramps the last three days, and sore gums with a metallic taste in my mouth the last two days.

My last pregnancy I don’t remember the metallic taste, but defiantly had the cramps.

Has anyone else had these symptoms and gotten a BFP?
