Mid-Cycle spotting

Hey ladies! My Hubby and I are TTC, and this morning, I had a small tinge of pink when I wiped, it has since stopped and I'm not sure what could be causing this. I had MC in 2012 due to having an arcuate uterus, and am worried about whether we will be able to conceive or not. Has anyone else had this? What could be causing it? PS, LMP was Aug 29th. Hoping someone can shed some light on this for hubs and I!
