Difficulty feeling baby's movements

R
I'm a FTM, 37 weeks, measuring small for dates, recently turned head down after being in breech for last 2 months.
Up until a few days ago, I was feeling clear, regular movements. 
I'm now getting regular tightenings, period type cramps and discharge - checked by my ob yesterday, he says all is fine but we might have a problem in relation to movement sensitivity.
My midwife put me on a fetal monitor and we could see plenty of movement which is awesome on the report, but I can't feel it, just the BH/tightenings.
I've been told by my MW and OB that I need to go the ob/hospital any day that I can't feel at least 10 movements - which is everyday now - any other Mums found this late pregnancy?
I don't want to be a pain but if I can't clearly feel movements, we can't know bubs is ok...
