number two

ok so i am losing my mind. I am on the mirena iud but i am feeling some symptoms of being pregnant. thsi can't be true. i have been told by so many people htat the mirena is said to be more effective than getting your tubes tied. Neal was home on r and r about a month ago. i ahven't had my period yet. but maybe it's just stress that is causing it to not come. i need to call and make an appointment to get the mirena taken out. i dont really need it anymore anyway. when neal gets home in januaryish we are going to try for another child anyway. and if i am pregnant again, omg i dont know what i would do. i dont know if i should just wiat for my period to come. i have always been irregular anyway. or if i should just test to put my mind at ease. when would be a good time to take a test? i haven't done this in over a year lol.
chey is 15 months old now. she is still too young (for me) to have another baby right now. plus i want my husband to be here with me during the whole pregnancy if i am.
sooooooooooooo hopefully im over thinking everythign and im not pregnant. we will see.
