Girls, good night! Could you please tell me, I have pulling pains in my lower abdomen and in the area of the coccyx-thoracic spine, like during menstruation but slightly stronger, for 2-2.5 hours already, period 15-20 minutes, pain lasts 50-60 seconds, don't understand if it's training or the beginning of contractions? During my first pregnancy, I initially had a plug come out in the evening, then pains started at night and then strong contractions, and in the morning I gave birth (there were no training contractions at all), as I was lying in the hospital, so it was easier, there were nurses nearby.
