I was ttc since last 14 months. I went to several OB/GYN and they’d put me on metformin and clomid and it won’t work!

And my periods are very irregular like I get in 3-4 times a year other than that I have no other peoblems. So on last Dec 2018 I went to a general physician near by home and first she gave me medicine to regular my period for 2 months. After that on march 2019 I was on metformin+clomid/letrozole and folicacid but unfortunately my pregnancy test came out negative. Then I had the same medicine for the second time and I got my BFP on last Friday. I’d say never lose hopes keep praying to GOD no doubt he can do miracles!
