Not sure if this is ok to post

Last month i found out my baby at 13 weeks had no heart beat...i should have been 16 weeks but baby died at 13 weeks :( i had to give birth everything looked normal to cut a long story short i wasent really bleeding alot after i had my baby..i went back to the doctor's as i constanly felt i was going to pass out they said everything was fine..it's been about 3 weeks and tonight I've had a very light bleed and it's stopped again i have no idea why has anyone else expienced this? If so was this normal process or could it be an infection? Sorry if I'm not aloud to post this on here X
