Still TTC

Hi yall. I conceived a year ago and miscarried at 7 weeks. We started trying again in September and my period started again yesterday. I getting so frustrated (it doesn’t help that I have had a friend give birth every week so far in 2020!) I have heard that checking your cervical mucus is the best way to tell when you are fertile. It sounds a bit gross but does anyone have any, uh, pointers on how to do it? Thank you ❤️
