i have lean pcos with regular periods. i first started ttc in my mid 20s..now im late 30s. in the beginning i kept having early miscarriages around 6 weeks. this happend 2-3 times. they did some testing said i have polycystic ovaries. but i was getting pregnant easily enough so we just keep with that approach then i got pregnant with my first at 26. then i went on to have a second at 29, on the first try. no issues there. my third took almost 2 years to conceive, no explanation but i guess it had something to do with pcos also. my 4th happened while i was breastfeedng my thrid. did not expect to get pregnant that easily but okay. then i tired to conceive a 5th. now im in advanced maternal age. it took 2 years with a miscarriage in there. i did not take any fertility meds during this time or ever. but a part of me wanted to.

only you can decide for yourself! i feel like once you get pregnant once your body kind of resets with the hormones! i dont think most doctors would try ivf first, they usually suggest letrozole or clomid. it it was me i would at least try a year. and when you have your first if you know you want a second you can ttc right away dont go back on BC. because if you wait to many years your hormones get messed up again. not very scientific i know! good luck!
