Opinions!

I’m 17 and my boyfriend is turning 20 soon we have our own apartment, we both own our vehicles, we both have good paying jobs (I’m a caregiver) (he’s a mechanic), our bills are always paid on time and we always have a little extra money. (Were going on our 3rd vacation in less then 2 weeks). We plan on getting married next September.. here’s the big part I want a baby but I’m not sure I can get pregnant (pcos). Ive always was told the longer you wait with pcos it could make it harder... do you think it would be a bad idea to start discussing a child? Keep in mind I’ll be 18 before it even arrives. Opinions!!! (Rude or not It doesn’t matter)

Edit- I’m also out of school, and we don’t do normal teen stuff we don’t go to party’s, we don’t drink smoke or do drugs, we don’t waste money to go out every time we get a chance. We pay our bills, grocery shop and normal put the rest of our money back into a savings (hence why we’ve been on 3 vacations in one year)
