I had a tubiligatin almost 7yrs ago this Oct. I have missed 2 periods, and feel extremly tired.. most morning I am sick to stomach.. no vomitting like my others.. my others I was sick around the clock.. I have headaches as I did in them.. I have read that yes you can get pregnant.. but what is the best way to see what is wrong.. - Besides the possibility of being pregnant what else could be wrong with me.?
