Good day everyone. Today I felt something strong on my left side, like in my pubic area and it was radiating into my rectum, pain like during menstruation, I got scared but it passed away after a minute, is this what they call pre-natal contractions? And another question, I have a constant problem, as soon as I start eating, my daughter starts pressing on my stomach, and even kicks with her foot, and appetite disappears, is this happening only to me or not? Week 35 of pregnancy.
