Hello girls! Small red bumps have appeared on my legs and slightly on my arms since yesterday. It itches sometimes. I can't understand what's happening (There are also swelling in my legs). Tomorrow I will call the doctor, the appointment is at 13, they should give me a referral to the maternity ward already, if not giving birth before this time. But I have to go to the doctor earlier now, as I don't want to (I am so worried that this could be, right at the end of pregnancy, 40 weeks.)
