On the younger side TTC

Kayla
Hi so me and my dh have been trying on and off for about two years. We have been married for 3. I have a couple conditions thyroid being one of them that have hindered the process. I'm on the younger side of the ttc scale at 21 and because of this I've been taking alot of criticism. Not so much from family and friends but from nurses and other medical professionals. I don't like to be rude to people who are helping me so I don't say anything but I'm unsure on how to proceed. Does anyone else have any experience with this kind of situation and how did you handle it? I feel the need to also add I graduated early and am well off in my career this is not a misguided attempt to create a baby to show me and my dh love each other lol.
