When peoples look at me and say "you're too young for fertility treatment"-

I'm 24 years old and I have pcos... I'm not too young for fertility drugs. We want a second child. We are having a hard time having a second child. I don't believe in the "it happens for a reason" or "it just wasn't in your plans". Explaining to someone why its so hard to get pregnant then to have them back hand you with "well maybe you aren't meant to have a second kid, isn't Emery enough" like I don't cherish my son. That my son isn't my sun, moon earth and stars. I want my son to have siblings... the "best" thing I've heard was "well since you run a daycare he'll never not be around kids... he'll have them to play with" and at the end of the day my daycare kids, his friends and his class mates all have families to go home to. He doesn't get to keep them like he would a brother or a sister...  I'm just so sick of people telling me to be calm or to relax. I am calm, I am relaxed. Especially now knowing that I have options and I am able to try fertility treatments... It is no one else's choice as to if Ed & I have another child. No one pays our bills... no one feeds our child provides for our child or does anything for our child but us! ugh. Rant over for now.
