Ugh so much money to get preggo

Katie • Stay at home mommy as of 6/30/16!!!
So I just spent $53 at CVS buying more prenatal vitamins Robitussin (which definitely did not get me pregnant last month but I'm trying it again to help fluid and CM even though I'm right at peak today tomorrow) who knows and pre seed  lube. Does anyone else agree with me that it cost so much to buy all the supplies to help us all get pregnant? I know my husband such a sweetie he was in the store texting me when I told him the prices and he said just buy it if it's going to help or least  we think will help 
I just have it in the back of my head I'll spend all this money and it goes down the drain every month when I don't get pregnant i'm on my 10th month  right now so hopefully this is the month that gives me the best luck ever 😬
