Number of children

So I have always wanted 2 children. Ive been trying to conceive for exactly a year now. For some reason im now 4 weeks late for Af. No BFP and no sign of AF. Very frustrating. More and more lately I have been wanting to have more than 1 child since it has been so hard for us to.conceive this time around. My husband and I already have a 3 year old daughter and have been trying for another. Im wanting about 4 children now. The longer its tsking me to conceive the more I want haha. Anyone feel the same?
