I am new to all of this and want to understand everything as best as possible to increase my chances of getting pregnant! I don't really understand how to figure out my cycle. AF came on the 17th and usually sticks around for 5 days. Are my fertile days right after my period?? I typically get my period around the same time each month, give or take a day or two. I'm getting my nexplanon taken out on the last day of my period. I'm also on metformin, 3 times a day and it keeps AF regular and my doctor said it helps with getting pregnant. I've been taking prenatal vitamins for almost 3 months now. Any tips or info is appreciated! Thanks!
