Worries about fertility after watching my sister struggle

Jojo

My sister and her husband have been TTC for 4 years. They waited a couple years before TTC until the "time was right". They have done <a href="https://glowing.com/glow-fertility-program">IVF</a>, <a href="https://glowing.com/glow-fertility-program">IUI</a>, and a plethora of treatments to no avail. They are devastated and are now exploring donor embryos because of their infertility.

Before my husband and I were married, I expressed my concern over waiting until "the time is right" (because let's be honest... is anyone truly ready???). I have been on Mirena throughout our relationship and he agreed that we should just let nature take over and see what happens. So I had my Mirena removed about a month ago.

I even bought an ovulation kit because I want to see if I'm even ovulating (which is my sisters problem), which I haven't used yet due to where I am in my cycle.

I feel almost guilty for planning NTNP with my husband, but now that it's happening I'm more pulled to TTC over my concerns of being able to get pregnant. I talked about NTNP with my gyn and she said "at your age (I'm only 32... ugh!) it could take up to a year" so I think that kind of sparked me to TTC.

Maybe I'm rambling, so I'm sorry if this doesn't make sense 100%, I guess I'm just wondering if it's normal or if anyone else has felt that even though they are NTNP, they feel like they are TTC in their hearts. I'm just so concerned that we won't be able to get pregnant (I know we are different and probably won't have the same issues, but I'm just scared). I want to be a mom so badly!!
