PCOS and SMBC

Hey! So I’m 23 and I desperately want to be a mom. I want to be a single mom by choice, as it is the best option for me at the moment. I possibly have PCOS but my doctor never formally diagnosed me. I’ve been ttc for two months with guys I know and have been unsuccessful. My family will not support me in this journey as they think a baby needs a mom and a dad. I have pretty much everything I need for a baby, minus diapers and clothes. I have a stable job but really don’t have a whole lot of money to spend on fertility treatments. Any suggestions?
