Sorry about your m/c
Umm from memory I bleed a little after things like sex, also vigorous exercise etc... I had a D&C, not sure if that makes any difference and it took about a month for my period to come back but its normal to take a bit longer. My friend who also had a m/c took 4 months for things to get back to normal.
if your worried though then go to your doctor and they will be able to reassure you.

Hi Tasha we recently had a "coping after miscarriage" topic where I put my m/c story but in brief, my next period came after 5 weeks, it was very crampy (Panadol stage for the first time in my life) and I bled for 2 full weeks! I checked it with the Doctor and he told me I was having a "clean-out" and it was a good sign. Your body can also have a break just like after childbirth (a few months to a year I guess, obviously breastfeeding won't draw it out like it tends to after childbirth).

I think you're fine and your body is still recovering. The reassurance of a Doc's visit is always nice And I'm so very sorry to hear of your loss, especially at 16 weeks
