Trying for baby #2

Hi everyone! My name is Courtney and I am 32 years old. My husband and I have a little boy who will be 2 years old on July 29th and we are beginning to think about trying for baby #2. It took us 11 months to conceive our son. I became very anxious and obsessive when we were trying for our first and I really don’t want to be that way this time. In fact, I had finally “given up” trying when we actually conceived and I believe that letting go and just letting things happen stress free really helped us. That being said, I have started tracking my cycles again just to get a good idea of when I’m most likely ovulating. The month we conceived, we only had sex three days- on cycle days 9, 17, and 18. I know there’s no way of knowing for sure, but do you think I likely conceived on day 9 or 17/18? My cycles average around 28-29 days. I know things change each cycle, pregnancy, etc. but I just wanted to hear from some of you. And those of you who have recently become pregnant, is there anything but that you believe helped? Like I said, I’m TRYING to be calmer this time but it’s so much easier said than done. I just really don’t want it to take close to a year again but if that’s what it takes then it’s definitely worth it. Thanks so much for any responses!
