Do Epilepsy Medicines Cause Miscarriage?

Hi Iam 35 years old n for the last few weeks thought that I was pregnant, my husband has been working away so I wanted to wait so that we could do the test together. I never got to do the test even though I had all the symptoms as I miscarried last weekend. I believe I was about 6 weeks but I am starting to think that as this has happened before this could be due to my medication for epilepsy. Should I go and see my doctor
