Periods after miscarriage

Nicola • Married. 29 years old. Mmc at 11 weeks July 2015 and mc at 4+3 weeks Nov 2015. Pregnant with baby girl due 30.07.17 ♡♡
Since my miscarriage my periods have been painful and have started with brown mucus turning to red spotting before the full flow. My periods were always full flow straight away and painless. Is this normal after a miscarriage?
