Have you been to a doc.?
I have had experiance with this~although I was32 weeks pregnant.
I had terrible stomach pains and 1st began throwing up blood this was a sunday I called my doc and when in the er and went black stools totally black!!
I was freaking along with my husband~they then found me to be in labor
over 6wks early.I was seen by a surgeon I was still throwing up blood and having black stools he told me it was my gall bladder and I was gonna have to have surgery to have it out!! My contractios were less than 5 min. Apart they put me in an ambulance headed for a bigger hospital they got the labor to slow down~ but by tuesday I was in and out of conscienceness and really didn't know what was happening wend. 4am I had to have emergancy blood transfussions and had our baby 9:30 that morning!!! I had a colonoscapy,throat scope while still pregnant and they found nothing to detrmine where I was loosing all the blood from~ after delivery they took me to have emergancy surgery to figure out where it as coming from~ they found a tiny tear on my stomach!!!!!!!!!!! So they asume that's where
i was bleeding from and after delivery the bleeding totally stopped!!!!!!!
And I have been fine that was over 3 years ago~
so it does worry me about black stools and yes other stuff can do that to you have you talked to a nurse or doc? I hope you have and iam sure you will be okay.But I don't think it's nothing to wait to long especially if you haven't been taking any meds that could cause a black reaction.
Will be thinking of you~how old are you?
