I always make sure to keep a clean in the bag and in a zipper of my purse Diva Cup for that. Always in the Safe Side haha. So I def know what you mean. 🕉💕
Could be just your body regulating after birth and cause you did Nurse for a month.
I'm that mum that with each Baby I do not get Period for almost 2 yrs lol. I also barely have pp bleeding too. So def could just be hormones regulating. If it doesn't show up next month ask ob to do an u/s and labs. 🕉💕
