I really don't get it

I don't get it I have regular periods they come like clock work I'm due the 2nd of December I just know it's going to show my husband and I have been married going on 11 years and stopped preventing 6 months into our marriage we felt like if it happens it happens and still nothing I'm 32 now and feel like I'm running out of time we want a baby now so badly but can't afford the testing to pay in one big lump some I just don't know what to do :(
