35+5 weeks pregnant

Chloe

Just want some advice .

I'm 35+5 pregnant . I went to hospital in pain and was stuck on monitor for while they said I was getting mild contractions. But I wasn't dilated . So they sent me home, but I've got protein in my urine and I feel sick and have tummy ache pain . Blood pressure is low though , does anyone else get this or is this sign of preeclampsia? So worried
