Do I ring maternity???

I’m 32 weeks and experiencing symptoms I’m not sure on.

-I have shooting back pains, nothing that is agony

-period like cramps in stomach/tightening

-my spine is killing

-I keep feeling sick

-I go and cold and get sweaty sometimes too

Today I’ve felt like I’ve had loads of discharge and I smelt abit funny (not sure if this is hormones as only bathes yesterday)

It’s my 4th baby so you’d think I’d know but I don’t want to waste time, last app was a week ago and she was transverse, I’ve been referred to physio for spd so not sure if it’s just that, I feel stupid if I go in and it’s nothing x
