Oh Mammycool thats terrible, your poor friend.
I know what your saying about a slowdown in movement, but I for one had lots of times on both pregnacies that I felt little or no movement, the think is if you went into OLOL at every time you were worried they would laugh at you….. for this reason I bought a doppler (60euro) on ebay and if I was worried I would have a listen to his heart.
This happened my dh’s cousins wife on Valentines day, only found out on Friday that there marriage has broken up with the stress, dont think the mummy is too well since, which is understandable
Your friend will be in my prayers
