Hello everyone, girls, what kind of mucus plug can there be? My belly started tightening at 37 weeks. I went to the doctor yesterday and she said that the baby hasn't dropped yet, so you won't give birth until then, like in 10 days, she sent me for an ultrasound. Yesterday, it was very tight before bed, I noticed some sticky, viscous discharge, this morning too, I feel like it's normal clear discharge or a plug ???‍♀️It becomes painful to go to the bathroom, such a feeling that something will fall out from there ?I'm already afraid of contractions, will I be able to endure them ?
