Welcome to the forum and congratulations on starting your TTC journey.

Many care givers will recommend starting folic acid supplements (or pregnancy vitamins that include the recommended amount of folic acid) anywhere from 1 - 3 months before trying to fall pregnant, so starting them asap is a great start

Like EJ mentioned, tracking your cycle is a great way to get to know your body better and increase your chances of falling pregnant by "doing the deed" at the right times in your cycle. I used a fantastic website online called "Fertility Friend" (you can google it) that is free. It has lots of great info on how to start checking your basal temperature each morning, how to chart your temperature, and also other symptoms (like cervical mucus) that can be listed on your chart. Based on all the info you put in the chart it can guess when you are most likely fertile and what date you are likely to ovulate. I also found that it was a great way for me to really feel like I was actively doing something to bring a baby into our lives (and for me it was fun, lol). Word of warning though... It can become addictive and you can become a little obsessed watching that little chart grow with your temps and looking at patterns.

I also headed off to my GP before trying to conceive to find out if there were any tests that I should have done. He sent me off for some bloods that included things like iron levels, immunity levels to certain diseases (like rubella) and a few other things. He also gave me a kit that we could use if we wanted to me to be tested to find out if I was a carrier for cystic fibrosis. It cost a bit to have the test done, but if it had come back positive you can get your partner tested for free. The main thing my GP emphasized though was the need to take folic acid supplements.

I wish you all the best and hope you TTC journey is a short one that leads into a lovely pregnancy journey for you
