In March, I had extremely heavy
(heavier than a normal period) bleeding, with large clots
(some the size of the palm of my hand). I called my OBGYN, and they said "this is normal. It's break through bleeding. We'll just move your shot up to 10 weeks instead of 12."
Well, about 5-6 weeks later, I started this same type of bleeding, but much worse. Soaking overnight pads in 45 mins. I again called my OB, and they told me to come in.
