Periods & mid cycle bleeding.

Leanne
Hi I was just wondering if anyone has suffered similar problems to me after miscarriage.
So here's what's happened, I had an early miscarriage in the beginning of January, had 1 normal period feb, my cycle was 32 days usually 28. All well and seemed pretty normal then I started spotting for 10 days from cycle day 16. Went to drs had swabs, checked urine all is fine and then I started spotting again cycle day 31, on and off. I'm unsure if this is natural due to hormones ect or if I should push for more tests. Drs don't seem overly concerned and I am feeling pretty anxious about all this and becoming very stressed so if anyone has had a similar experience or has any insight I would be very grateful.
Thanks
