I just stopped taking my birth control about a week ago but two weeks ago I was on antibiotics. My birth control is the kind I consistently take even through the placebo pills. On Monday 1/13 I started spotting and it was very light and now it's been four days and is still not heavy but it's a redish brown color( with some blood clots). My lower back has been aching, I've been feeling dizzy and very exhausted. Could this be implation bleeding or is it just my period? Also I have unprotected sex

Implantation bleeding doesn't not always occur but when it does, its approximately 4-7 days before your period is due and it does not last for several days.

You took antibiotics two weeks ago, then stopped birth control a week ago... are you trying to conceive? If not, get another method of birth control.

I wouldn't mind if I was pregnant my husband and I would be happy. I just don't know if implation bleeding would occur that soon, plus since I normally don't get my period because of how I took the because pills? Oh also before I took my antibiotics I has my period for 4 days

Of course I can't fully answer, only a pregnancy test or a period in a week can.. but when you quit birth control, for many women, it takes most women several months to become regular again. Brown/red blood with clots does not sound like implantation bleeding, it sounds like an impending menstraul cycle.

I'm just very confused

Thank you!
