Devastated

My bf just told me its okay baby maybe its just not meant for me to have any kids. This just broke my heart. I suffered two miscarriages in the last two yrs and i suffer from severe hyperemesis when i get pregnant. I got on depo after last miscarriage in oct 2016 and stopped in april and still not pregnant yet. I have used opk and all and still nothing. Just got my af and im so devastated 🙁🙁
