How do I stop worrying about getting pregnant?

I have been trying to conceive for over a year and a half. I have finally gotten clomid I am currently on cd 4 and day two of taking clomid. I have been researching for months. I find everyday I am looking for more information. I know I'm wearing myself out, but this has almost become and obsession. I have one child and for some reason I am terrified I won't have another. I have three more days left of taking clomid. I plan to bd everyother day starting the sixth of june. I also have been taking prenatals, I plan to use mucinex to help with cm, and preseed, I also plan to use baby asprin to help my uterine lining be more suseptible to implantation. Any further advice, words of encouragement, or even just let it go and have fun is appreciated I can tell myself this all day but until someone else tells me it won't matter....lol
