Spotting before period?

Hello all,

My partner and I want to start trying for our rainbow baby in August after our wedding. My miscarriage was over a year ago but it wasn’t anything wrong just one of those things. We decided not to try again until we both felt ready and now we are after our wedding.

What I’m worried about is that I’ve always had normal periods and never any spotting, but this cycle I’ve been having very light pink tinged discharge when I wipe. It started last night but I’m not due for another 3 days. I’ve never had spotting before and I’m not sure if I should be concerned or not. I’ve been seeing a naturopath for a while for some digestive issues but they are being resolved and I’ve also started taking zinc in the past week.
