I tripped over last night on the stairs and fell on my front - was falling up the stairs so not a huge distance IYSWIM - and now am terrified that I've killed the baby. I'm 20 weeks and have been feeling a bit of movement for a while but not particularly regularly. I think I've felt a couple of movements since but might have been imagining it; but it's only been 10 hours. No bleeding or anything. Should I call the midwife?
