Spotting issues

Nicole
So I have been TTC since November of last year. Had a miscarriage in February and trying again. But there is a problem I am starting to become confused with my period because I am spotting literally all the way to my next period. These past two months it has happened. I am thinking no big deal but I feel like now this may be causing issues with me becoming pregnant again. Because I am not sure if a period has really ended. I am going to call my doctor this week to go in for a check up. But has this happened to anyone else? Any advice? Also I have never had this issue until after the miscarriage!
