PCOS TTC

So, my boyfriend and I found out why we were having some difficulty getting pregnant about two months ago. Yup. You guessed it, the horrid PCOS. My dr won't start my on fertility medicine until Feb because it not considered a "fertility issue" until 12 months of actively trying and I was unsure when we technically started trying. I'm not even sure if I wanna start fertility medicine anyways I'm kind of on the fence about it. Anyways, we have just been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> through glow and trying to get pregnant naturally. Well.. I'm supposed to start my period on Jan 7th and tonight my nipples are very, idk how to exactly put it. But they are tingly. Like I feel like there is a shit ton of electricity in them. Could this be an early sign of pregnancy?
