I’m 2 months 1 week after birth with second baby and am exclusively breastfeeding him. Yesterday I thought I was starting my period when I saw a bit of blood when wiping. But nothing more came out. Now I’m feeling on/off period cramping for the last day but nothing more coming out apart from a couple more very light traces when wiping. I assume this is my body not being sure whether to have a period— ok but how long will the PMS go on for?? I didn’t have this with my first baby. Any clues and/or should I contact doctor? Thanks.
