This is my third pregnancy and I thought that I could feel the baby moving last week on Tuesday and Wednesday - lots of tickling feelings from the inside. I mentioned this to my midwife on Thursdsay and she said that it was quite early - I was 15 weeks then (and 15+4 today) and that early movements were really hit and miss. All was well at the appointment and I heard the heart beating. I haven't felt much at all since then though. Are movements early in pregnacy really hit and miss or should I be concerned?
