I had full bleeding period that was bright red and was very scared at about 16 wks, but it was a bloodclot...dr said it has two jobs. . My body would absorb it or release it... get checked it might just be that. .. you can also spot after sex... I'm 35 wks now and all is well. Just don't stress because that's not good for your body. ..Hope all works out for you:)
If you are concerned call your doctor or midwife or go to the er
