Not sure how I feel...

My partner and I have been engaged for 2 years and been ttc for 1 year & six months.. I have PCOS so it's not very easy! I'm feeling very discouraged... I'm currently taking 1000mg of metformin a day and we have sex every other day, I get the feeling that I may not be ovulating? I've done tests but they are never exactly as dark as the control but are very visible! what should I do? if anyone out there has PCOS and has got pregnant what did you do??? Please give me hope! 🙏
