I had a light and late November period with brown spotting only (on nov. 15 & 16th). Then from Wednesday, Nov. 26 to Dec. 7, i had light brown spotting; once or twice each day. Two (only) of those spotting had very slight pink with the brown. Sometimes i did not see this old blood until i wiped after peeing.
Now, brown light spotting started again during December period time. Begining yesterday, wednesday(dec 10). I am 24 and married and on birth control pills. We have sex regulary about 2 to 3 times a week. We do not use any other birth control other than the pill. I have also taken a home pregnancy test this morning with my first pee. What could be the possibilities of this brown spotting and random in the middle of month (between periods), week and half spotting? Thank you for your time and consideration!
