I've been on vicoden for migranes for about 6 months now and my huband and I have been trying for our 2nd child. since we started trying every month my period has been 1-2 weeks late. This months cycle for the first time it will be 4 weeks late as of this coming saturday. I have taken many pregnancy tests and they are all negative. My breasts are very tender and my lower abdomin is tender, which started at the same time. I am going crazy here with getting my hopes up and dont know what to think. Is my period missing because the vicoden or is there any chance that i could be pregnant? I need to know so i can find other ways to manage my migranes if there is a baby in there.
