Does lamectil negate a depo shot?

i recomend this. my first round i got it in my arm it hurt for a week. then on my second round i asked to get it in my butt it still hurt but did not affect me as much as in my arm.

In many cases, yes, it does. Though I've heard of many women who have some break-through bleeding and/or spotting with Depo.

Once every 3 months.

No. I recently talked to my doctor with this same question. I was on Amelox which is a form of amoxycillin antibiotic for a sore throat. He told me that depo isn't effected by antibiotics and that...

Yes it is possible it happened to a few of my friends and family members but its only like a 1% chance though
