I'm 17weeks gone and I have felt some really strong movements (normally waking me at 5:30am and continuing for an hour or so). This morning however, there has been nothing. Ive tried the cold water treatment, a hot drink, a brisk walk to town to catch the bus for work and nothing seems to have worked. really worried. Midwife not open for calls until 9am so will call then. Anyone got any suggestions or reassurances?
