So I were admitted to hospital 2 weeks ago with pains and fFN test came back positive but allowed home the day after. Then Friday I kept having tightenings and bad back pains so went back to hospital. Checked me over and another fFN test came back negative then pains went again. Since then I'm having tightenings and lots of pressure down below. Same as Friday. Anyone else going through this? I'm 33+3 weeks X
