Hello, I Was 16 Weeks Pregnant And For Personal Reasons

Hello, I was 16 Weeks pregnant and for personal reasons had to have a surgical abortion on November 15 2016 (about two months and two weeks ago) a week ago I thought my normal cycle had finally started, but then 2 days later the bleeding stopped. I'm still spotting ever since the abortion. Sometimes I spot for 2-3 days sometimes I don't spot for 2 days and sometimes it's a little heavier. I haven't had any cramps or fevers ever since the abortion. Maybe a few headaches but I usually get those. The blood can rage from light red to really dark red almost brown. There are days where a shrimp like odor can be smelled but that squally happens during the 3rd day of my period and last. I don't think I've had my period yet. My breasts are still lactating 2 months and 2 weeks after. I don't know why the blood color changes all the time and why I sometimes bleed and sometimes don't. Please get back to me as soon as you can thank you.
