Hello everyone! Today's due date is 37.4. I feel terrible, all my muscles are cramping at night for two days now, and my lower back hurts. Frequent discharge has appeared, and what's more, it hurts when I walk. Sorry for being frank, but I'm talking about my vagina...? Is this preparation for childbirth or how can I understand it? In my first pregnancy, everything was completely different. I'm worried that I won't give birth on time...
