I'm wondering If there is anyway I could have been pregnant and miscarried. I have been on my period now for 7 days and it is bright red and I know it sounds gross but every time I use the restroom there is what appears to be clots or tissue like substance. If I were pregnant and miscarried is there a way not to find out if I was with a pregnancy test or blood test and should I be seen by a Physician?

Go to the doctor, that's the only way to find out.
