Pelvic girdle pain hun. I have this same feeling. Have had for weeks and with previous baby. Uncomfortable to walk, sit down and lay in certain positions. Defo pgp i reckon. Nothing u can do 😭😭😭
Could be mucus plug… call triage
Does it feel like there is a heavy ball there, it could mean that baby is startinf to go head down. Ask on your next appointment if head is engaged.
