Trying To Get Pregnant!

So Me And My Fiancé Have Been Trying For A While Now. I’m Just Super Ready To Break The “I’m Pregnant” Announcement On Christmas As A Gift To My Family ! I Just Don’t Know Where To Start. Like Every Time I Ovulate We Always Try And At The End Of The Month I Get Disappointed Because My Menstrual Comes On 😒😩 Somebody Help Me Please. Lol Honestly I Just Need Guidance. Like what to do. When to do it. Because we are so Ready and Eager To See That Big Fat Positive!
