let the madness stop!

My husband and i have been actively trying for over 3 years now. ... before we toyed with the idea, kinda like whatever happens happens. and as time went on and months passed i kinda wondered why it hadn't happened. i'm almost 23 years old now, i "shouldn't" have these problems.. so i thought and boy was i wrong. i have had so many different doctors prying at my girl business, and so many different test and tried everyone of their "solutions" to fix the problem. i traced ovulation using, calendars, the microscope, easy clear plan detector. people are constantly asking when were going to have a lil one.. after all my husband and i have been together for almost 5 years and married for 3. yeah it should have happened by now.. our parents ALWAYS make comments while shopping "wouldn't this look so cute if you had something to put in it" holding up little onsies and outfits. i'm like yeah you have no idea. to make matters worse his mother is a nurse... with 500 billion questions. i am the 2nd oldest out of 4. with my dad marrying and inheriting 2 more children 1 older 1 younger. since i have been ttc; my stepsister got pregnant, my cousin (now on her 2nd) my brothers finance, my other cousin, and 4 of my friends... finally after the never ending rude comments people asking me "are you pregnant yet" and the one i really love at a baby shower "so when am i going to be getting and invite to yours?" as if buying all the gifts and actually attending the shower aren't hard enough... now i get bombarded with questions.. so finally last summer i freaked out and told everyone were trying. having a hard time it'll happen when it happens and lay off.. to no avail they still make comments and still ask questions. now maybe even more.. i pray the madness stops and we become pregnant...i dont know if i can take much more..
