Dull achy pain

Alyssia

Ugh. I fear it's going to happen again. we just had a Miscarriage in August and were cleared to try again right away. well I got my BFP on Sept 15 and it was pretty dark. I'm having some dull pains almost like a throb or a pulling or sharp... idk how to explain it but it's been on and off all day. should I be concerned?
