Due to many symptoms i've been thinking i could be pregnant but...?

There is a possibility that you could be pregnant, I would take a test. However, stress can also affect your period being late. My husband and I had been trying and one time I thought I was but wasn't, anyways I went to talk to my doctor who told me that my period was late because of stress. However if you feel you are having symptoms I would highly suggest a test. So try not to think about it TOO much and go get a test, they aren't very expensive a pack of 2 digital tests is about 9 bucks! Best Wishes.
