I was trying to conceive for 7 years before I got a positive ovulation. I conceived my son with Letrazole but with this meant my son need 2 minor surgeries (Not saying this is going to happen to every one) me and my partner wanted to try again but all the appointment etc had to start again (xrays, bloods, scans etc) so while I was waiting to be referred I came across this and laughed at how they stated if had higher success rates to Clomid, letrazole (femara) "a vitamin ha yeah right" but brought them to see. 14 days later I was ovulating 😯 wow it worked. I think if your in this situation please have a try as there's no harm in it and you never know it may help you. Please message if you have any question and if you try them will be nice to hear you story too 😊😊 good luck
