Girls, advise me what to do, the period is 35 and 6 days, I'm cutting pain in my lower abdomen from the right when I walk and when I turn over from one side to the other, it's strange that I cry just like that without a reason, I'm happy, I don't seem to be straining today, I went out for errands and spent the whole day at home lying down because of the pain, I'm still struggling, I can't breathe normally and walk around, it's really bad? and the baby is active, in short, I don't know what to do
