Hello, I am 42 years old and have a 13 and 10 year old. My husband and I for 15 years have used no contraception. I have had 1 known miscarriage 7 years ago. My period usually starts between 22-27 days, a few months ago my period lasted 11 days which was very unusual. Now my last period was April 17th which was 33 days ago. Both pregnancies I was put on progesterone because I was low. I have taken a urine pregnancy test that was negative and 2 days ago had a quantative test that came back negative. My Dr. said not to worry and that some women miss periods all together. Is their still a chance that I could be pregnant?
