Is it implantation bleeding?

I'm confused as to whether what i am experiencing is implantation bleeding or not. I am currently on birth control and notice a brown residue when i wipe after using the bathroom. But what confuses me is that i have finished my more or less 10 days up to that time. I'm not sure if i could be pregnant or not. I started my extent on the jul16th and finished on the 20th.
i have unprotected sex only just a few days after (on the 23rd) and notice the bleeing on the 27th. I'm soconfused as to what it could be. One entry that i'm hoping it could be is that my body is react to the reality that i missed 2 pills on my BC and started up again.
does anyone know what could enjoy cause the bleeding?

Fainting when using tampons..?

you may become pregnant at any time you own sex, and thats when implantation bleeading shows up. although missing a pill its also a possiblity. A lot of times during birth control you will own a discharge from your vagina. Theres plentiful side effects to the birth control.

i suggest that you hang around for your subsequent length and hold on to up to light of day beside your pills. also when you miss a pill its really essential to use any other put money on up meathods such as condoms.
a month from immediately pinch a home pregnacy experiment, or budge to the doctor. Remember no form of contreceptive is 100% efficient.
