Hello everyone! Excuse me in advance for such a question. In the evening I went to the toilet twice, big time, lying down and can't fall asleep from insomnia, got my stomach ache, thought I would go again to the toilet...went, sit, my stomach hurts, feeling like very much want but not coming out, like empty, but strange feeling like very much want doesn't pass. What could it be? How does childbirth begin? Please tell us ?? It's still early, 31 weeks and 5 days.
