SPD in pregnancy

I'm 22 weeks pregnant and I'm getting pretty uncomfortable pain and discomfort in the front of my pubic bone, its getting increasingly worse. I spoke to my midwife and she has said I need to refer myself to a physiotherapist, however they are not taking any referrals at the moment (covid)

Its getting so bad, that I had to walk up the stairs one by one today. I don't know if it is SPD, I'm just self diagnosing.

Does anyone have any tips on what to do?
