TTC after miscarriage

Anyone TTC after miscarriage? I miscarried 4/28 at 8 weeks, bled for about 6 days and then got AF about 5 weeks later. I decided not to do ovulation tests because I can't ever get them to work! Didn't want to waste money😉 
However, around when I thought I would be ovulating, after the DH and I DTD I spotted for about 3 days. Nothing really requiring a pad, but it had me freaked out. Has anyone experienced this? I coach cheerleading and was at cheer camp all weekend so we were unable to BD as much as I would have liked to. AF is due 7/2 according to glow, but i think being pregnant for 2 months confused my dates. Anyone else in their TWW right now?
