Oh yes that sounds just like me! I have two young children and I spotted like crazzy after my 2 deliveries (2.5 months!!! for each!). I was going crazzy!!
After AF (which is always with me for a good 6-7 days) I can spot for a good 8 days. It's always so depressing so I totally understand how you feel! I never know when it's going to end!
But the good thing is that I've been on met for over 3 months now and this last AF, after the bleeding was gone I only had 2-3 days of very light spotting!

Met takes time to work but it should help you if you stick to it!!
Good luck!
