Since 3pm today Iv had diohrrea (had about 7 loose bowl movements so far) and I don't know why, I can't think if anything that Iv eaten as only had a sandwich and a bag of crisps for my lunch and my husband had the same an he is fine. Iv had some toast for my tea as I didn't want anything heavy as I'm worried it could carry on through the night. Is there anything I can take? Eg immodiun? I'm 23 weeks.
