Bleeding/spotting for 30 days

Ok so my husband left the country to visit family for a month last month (yes i was stressed because of how terrible service was and etc) - we had sex right before he left then i started my period the week after around the 18th, it started off brownish then got heavy, then lighter eventually just spotting. The problem is the spotting never stopped up until the first week of july. It stopped for a few days then picked back up towards the end of the week. My husband is back in town and the spotting continues, not enough to drip or create a mess everywhere (tmi i know) but when i wipe its obviously there. now its just brown (sometimes pinkish mixed)....im not taking any BC. Is this normal??? Its starting to scare me.
