I just had 2 days of brown spotting then it totally stopped 2 days ago. I have a 4 month old that I am exclusively breastfeeding. She is my 4th child. With my 3rd I got my period at 4 months when I also was exclusively breastfeeding. My husband and I use condoms, but had an accident at the end of May. I am just wondering if anyone had this and ever found out what it could be. Thanks!
