Need advice and baby dust for baby #1!! πŸ™πŸ»πŸ‘ΆπŸ»

Victoria β€’ I`m a 34 year old married woman! I`ve been with my hubby for 10 years and we have a beautiful 5 year old little girl and a 2 year old little girl! We’re TTC #3.
My DH and I have been together for 5 years, married for almost 2 and we are finally in a place where we want to start trying for a baby! I'm so nervous and pretty much every emotion under the sun, but I'm such a planner and perfectionist. I will lose my sanity if I can't have any sort of control over this process! I know I can't have everything down to a science, but I want to be as prepared as I can be! I have as many things for the process as I can, but I saw that there are different brands and varieties of fertility teas and things that won't harm your chances. I'm looking for something to replace my coffee...any suggestions!?!Β 
Thanks in advance ladies!!
