I'm about 4 weeks, almost 5. I just had my 3rd positive test last night, but this morning I woke up feeling so normal. My boobs weren't sore and I could keep food down. I had some light cramps and back pain, but I didn't think anything of it. Then I noticed while wiping red blood. I bled for a little under an hour and then nothing else. I noticed my cervix still soft but lowered and slightly open. Am I having a miscarriage?
