Clomid TTC QUESTION

Okay, my husband and I have been TTC for 1 1/2 years. I have already completed 2 months of Clomid at 50Mg. Has anyone else used Clomid? Did you up the dose at some point or change the days you took it? How many months did you take it and did you have to have test done during it?? Certain sex position ideas or times? Plz help just getting discouraged and would love positive feedback. Thank you:
