After giving birth...

Hi mga sis, gusto ko lang magask after 2 months ng inyong panganganak, nararamdaman niyo ba na pag nakatayo kayo for a short period of time parang masakit sa private parts na parang may dumidiin. Is it normal? Hehe ayoko na kasi lumabas para pumunta sa hospital kung normal lang namam siya. BTW I had my IUD right away after lumabas ni baby so Im thinking it has something to do with that.
