basically...

dec 10-13 period

dec 22  sex w/ condom

dec 27-31 period

jan 02 sex w/condom

jan 05 dark brown smudge that only happens at night. (with a fishy smell)

 

some things that might be of help:

i used emergency contraceptives on july then sept, then stopped using them after. 

my period is usually on the 22nd of every month, then suddenly shifted to the first week of the month starting november.

I used to have the same light brown smudge before like 2 years or so, but eventually went away.

 

is this IB?
