Last month my period lasted 3 days, which is the usual for me. I ovulated on cycle day 13, as usual for me. Then at cycle day 6 and 7 I had brown spotting. I took a test at 11dpo and it was negative. I got my period again on the 17th, the day it was due. This time it only lasted a day and a half. I'm now on cycle day 12, negative opk and I woke up with brown spotting again, I've had it all day long, it's not much, just when I wipe. I was having cramping on my right side so I thought I was ovulating but as I said before, negative opk. I'm about to call my doctor to get a check up but I was just wondering if anyone have ever had this happen to them? It's all very new to me because I never ever bleed mid-cycle like this and I've been getting a period for 11 years now. Any help would be appreciated!
