Hello everyone. Girls, who is from Astana, I'm 18 years old, first pregnancy, give me some advice on what you can do that you shouldn't do? From what month should I stop taking birth control pills? What food can I eat and what not? I don't know anything at all ? There's no belly yet for 4 months ? On the 24th of the month, 2nd screening, then they say gender?
