I had missed my period and had all the symtoms of being pregnant, but got a negative home test. I went to the doctors on Wednesday for blood work and it came back postive that i am pregnant. Last night i started to bleed and it was brown, as if it was old blood from maybe left over period from last month. Today it got worse and it's like having my period, red blood, regular flow. No cramping really, just the slight cramping ive had for a week now from the uterus stretching. I already had implantation spotting last week before my missed period, what could this bleeding be? Should i be worried about a miscarriage? It's started to slow down tonight, i took another blood test today to check my levels, i get results on monday. I still have morning sickness, sore breasts and all the other wonderful signs of pregnancy, (my breasts started to just get sore today) should i be really worried? I'm so nervous, i'm only 5 weeks along. Any advice? I've heard some women do bleed through out pregnancy and theres no explanation for it, it usually stops.
