6 Months Postpartum. Started Heavy Periods With Clots, Occasionally Getting Light Blood. Is This Normal?
The way that your uterus is behaving is not normal. Especially with regard to the description of "gushes" of blood and clots. It suggests that there is something anatomically different about your uterus, such as fibroids or a polyp.
This is pretty far from delivery, and with the intervening normal periods, I would say that this does not sound like retained placenta (which might present like you are describing within the first 1-2 months after delivery).
Based on the amount of bleeding, this does not sound like you need to be seen tonight, but you doctor needs to be contacted tomorrow and you need an exam and an ultrasound. This is the best way to sort this out!
If you have more questions, please ask.
