Jac
Sorry for long post!! 
Saturday day had a few drops of light pink, thought nothing of it, slowly increasing  in colour and amount day by day till Tuesday when discharge was definately pink all day.
Started getting shooting pains down there Sunday/Monday, she's defiantly dropped and at last midwife app her head was 4/5 engaged.
Got period cramps but it's more my back that's hurting , shooting pains still
, was sat having wee Tuesday night and suddenly my right hip jsut felt like it went with a pop and moved , took my breathe away ,
Woke up today feeling all aches and sore in my pelvis and too of my legs, occasionally tightening s of belly with some pain. 
Should I go hospital or jus twist till midwife next week??
