30 weeks and boobs are leaking and have been since 16 weeks, I just started back with my primary OBGYN I haven’t seen her since week 8 because I had to rotate with five different OBs in case they had to delivery my son well the others knew my breast had been leaking and today was the first time I’ve been back with my OB and she said I could be storing it with nipple shields and freezing it where would I find them and how to do this
