You are 7 weeks pregnant and experienced brown spotting for a couple of days then you noticed a clot of white tissue mixed with brown bits you have had no further bleeding could this be a miscarriage?
This is no time to be sitting at the computer asking us if you are having a miscarriage. Hopefully you aren't, but it's extremely important that you get to your doctor immediately and if he/she can't see you then go to the ER. You baby will be monitored. DO NOT DELAY!
