I’ve just posted this on another thread about PGP, you may benefit:
I'm 27 weeks and I have pretty bad PGP. It does sound like your symptoms are PGP and I do think you need to get it looked at rather urgently.
I've been going to an osteopath who also does acupuncture, but that is expensive. My midwife has also referred me to a physio to help me out, I suggest you do the same ASAP.
What I've learned is that:
PGP should go after birth.
Walk slowly, avoid standing, heavy lifting etc.
Ice packs on the pelvis area or heat (hot water bottle) to your inner thighs to relieve pressure on your muscles that connect to your pelvis.
It is the everyday activities that are aggravating it, so you will need to be more mindful such as, sitting down when putting on your shoes. Sitting down when changing your underwear, trousers etc. Basically, no standing on one leg.
Moving in bed, keep your knees together.
Moving in and out of the car, keep your knees together.
Keep doing pelvic floor exercises or find adapted yoga poses suitable for PGP (which mean keeping your knees together).
Paracetamol if you're in pain.
Epsom salt baths are really nice too, but be careful getting in and out of the bath (knees together).
Order a pelvic support belt from amazon, mine was £13 pounds and worth every penny. Wear it when you're moving around, take it off, or loosen it when you're seated.
It likely won't go away before childbirth but you can do things to manage it until birth. Take it easy, ask for help, and keep your knees together.
I hope that helps
