Spotting two cycles post miscarriage

Is it normal to have ligt spotting through whole cycle? I'm 2.5 months post miscarriage and this is my second cycle- this didn't happen last month but I had a crazy long period in my first cycle- 10 heavy days- this cycle was only 5 days (normal for me but I started spotting on cycle day 14 and have spotted for about a week every day- we had sex 5 out of 7 fertile days
