Started bleeding again 4 and a half weeks after a section?

Hi I had an emergancy c section on the 8th of feb due to the fact my placenta abrupted. Unfortunatley my baby girl was born very ill and passed away on the 9th in my arms. The full story is in the bereavment forum. Anyway I have started bleeding again today and am wondering if this is my period. It's not overly heavy so I'm not to concerned just curious. I have got a slightly crampy stomach aswell. I'm sure the doctor said it would be around 6 weeks before I got a period? Any advice? Xx
