OMG WHAT A GREAT THREAD!!! sooo I have been lasering for a while now on my face. Due to tons and tons of stress over the past year I have gained a significant amount of weight and here follows PCOS. So I went to my obgyn (i’m Not married) and my doctor said the hair growth can be three factors: my thyroid, possible pre diabetic symptoms, or pcos. I was concerned because I’ve always been regular but for the past few months I have missed my period etc. I had all the blood work done and everything came out fine. Because of extra weight gain your testosterone levels get high and that is why you grow extra facial hair. He prescribed yaz because it helps with normalizing your testosterone levels etc etc. I had been on yaz last year for endometriosis but after three months on it I was spotting so I decided to go off it. If you go on birth control to control your pcos then when you go off it depending on whatever the reasons are that caused the pcos in the first place, the hair is likely to grow back. The birth control “masks” pcos symptoms but does not solve the problem. You need to look at what may possibly be causing your pcos and work on that so that if you need to go off birth control then you won’t have hair growing back. As far as birth control and wanting to get pregnant, that is something you’d have to ask your doctor but there are plenty of women who have been on birth control for years, go off of it to try and have a baby and after a couple of months they are pregnant 
the best thing about birth control is that is makes you face glow and gives you the BEST skin ever
