Same for me, I also had clots two weeks out with my babies. I always tried to do so much before I was ready! But I also think it can just happen for other reasons, like whatever secret healing process the uterus is involved in. But the main thing is, take care of yourself and rest, and I would not stress about it. But if it kept happening, yes, I would for sure get your care provider to check you. Chances are it won't keep happening though. Interestingly enough, this is the first time I've been extremely careful about resting and not overdoing it, and the first time I've had minimal postpartum bleeding and no clots and stuff. But you know, I still think there are other factors involved than our activity level, even though rest is crucial.
