Have you had an ultrasound done since? subchorionic hemorrhage is like a blood clot in the uterus that can cause you to bleed a little or a lot depending how big it is. Like blood clots they are either absorbed by the body or bleed out, like you're having your period (and yes you may experience cramps). I believe this can happen any time during pregnancy. Depending how close the clot is to the baby, it can cause a miscarriage. However if its no where close to the baby and in subsequent ultrasounds you see it getting smaller, you and your baby should be fine. The most important thing is the heartbeat is healthy and the baby keeps growing. I suggest to get an ultrasound done to rule this out. If it is ask your doc what you can do. I hear bedrest is required. Im not aware of any other conditions that may cause bleeding. You should ask your doc.
I still can not keep anything down. I went to the er a few nights ago and the doctor say I'm going to need a permamnent iv since I still not able to keep any food or water down.
I hope it is not a m/c hun! I am too 11 weeks and bled 5-9 weeks all the way. Sometimes a lot & sometimes a little bit. Also had cramps and found it difficult to walk. Docs could not tell me what was causing the bleeding. It happens so please don't stress. It is not good for the baby. All will be fine xx
