wa'alikumsalaam sister

Jazaka'Allah for your words it feels so good to share things alhamdulillah for your sisters.

my sister in law had PCOS and she was taking metformin fo almost 2 years or a bit more than this... during taht time she conceived a year ago and miscarried. Allah knows BEST as HE is the BEST PLANNER! Alhamdulillah she conceived again in this april.. she took clomid it didn't really help her but what i see that helped her was losing weight but you already said that you actually need to gain weight she was having problem with ovulation her periods were regular... once you ovulate I think you can try IUI as it's close to 300 or 500... I am just trying to help sister.. Allah is going to make it happen when the time is right iNhsa'Allah and keep making dua.
I hope it helps... and with my husband he lost weight and it has improved alhamdulillah...
