still in "false labour" anyone got experience with this?

Anyone else in the same boat as me? Been having contractions every 4-10 mins for 3 days! Constant excruciating back pain. 2-3cm dilated. Went in today for monitoring and midwife said I'm having really intense contractions but loads of little ones too that are all over the place so it isn't true labour. I've had 2 sweeps. Has anyone else experienced this? I'm losing it now, don't know how much longer I can cope!
