What do you think, am I pregnant? Nobody's answering!?

I believe that im pregnant but its too early to test. I am on Methodone for pain and im wondering if these are side-effects of that or symptoms of pregnancy. Light headaches, extreme fatigue, out-of-it, light nausea, super sore breasts (methadone helps reduce that for me), thirst, mouth watering, light cramping, body feels off-balance sometimes.
