contrave for weight loss to hopefully fall pregnant

after 2 failed rounds of letrazole and 6 months on metformin through a fertility specialist, I decided to take a break from TTC and ask my GP for contrave since her original plan was for me to lose enough weight for my periods to regulate and fall naturally like I did previously...

Now I’ve lost 8kg and my period is here after 72 days.. obviously the medical direction is not to conceive on contrave but the actual medical evidence for this looks limited. Contrave only stays in the system for max of 48hrs and can be stopped without tapering... if I was to try and have a miracle I would be testing from 8DPO..

Has anyone with PCOS fallen pregnant while on contrave or have any experience with this??
