Okay heres my story, i've been on the depo shot for about 3 or 4 years now. In the begining i had a little bleeding, which i know is normal. Lately i've been bleeding pretty heavy for a day then i will stop and it will start back up in 3 days or so. Then quit again after a day or so, then start back up. I haven't bleed for about a month or so, and last night i started bleeding again. It was a pretty heavy and really really dark. The color of it was brown almost. I'm just wondering if this is normal, cause for alarm? Any advice or info will be appreciated! Thank you!!
