To everyone good night! For someone it will be strange, but (!) I've started contractions, I can't understand if they are training or real ? because I feel this for the first time. Before that there was none. First pregnancy. Pain from the lower abdomen radiates into the lower part of the spine. And excuse me for details, I really want to go to the toilet, as soon as I sit on the toilet, such a feeling like a baby is pressing on the urethra and anus. What do you think, is this real?
