Period weight gain ??

Alisha

Ok I e been having real issues with my period over the last year and a half and it’s been all over the ply. I stopped BC after 17 years (ovarian cysts) in February and didn’t have my period til end of June then didn’t get it again til Monday. Friday afternoon I had bloodwork done and I weighed 135 and I JUST weighed myself at home and I now weighed 143.5! Is this even possible when I have barely been eating?
