Have been having very painful contractions for around 30 hours now (every 10 minutes ish). Have barely slept and feel awful but managed to drag myself in for a sweep today. I was told I am 2cm dilated (first baby) and my cervix is fully effaced. I have had some blood since the sweep and the contractions are becoming more intense/painful and like shooting pains rather than period pains. Any estimates as to how long it may take to become fully dilated? I just want some gas and air...
