So I'm 17wks 5d prego and I've heard the heart beat it was 150 the nxt time diff day was 148 then yesturdsy it's in my notes 142 but I recorded it and it was jumping 142 150 156 then in the notes 142. I can't really feel much movement I thought I could. But midwife said she has no concerns and the heart beat should fluctuate, has anyone else had this?
