Today exactly 39 weeks, all day I feel unwell, since 5 am I've been having stomach pain, then it stopped, throughout the day I feel tired and want to sleep, I don't want to eat, started stabbing, cutting in the lower abdomen. Yesterday for a whole day I went to the toilet 6 times, excuse me. I don't know if it's starting or not, I don't understand, maybe someone had such an experience ??
