tips on TTC

Ashley
I'm 21 years old and me and my boyfriend have been trying to conceive for about 3 months now, using the app and doing everything by the book, but I got my period yesterday. We have sex at least every other day and every day during my fertile window, I keep my legs and hips up after, eat healthy, and get lots of rest. Is the any over the counter vitiams or pills I should and should not be taking. We are trying for our first. I saw a doctor a couple months back and she said everything looks good for me to conceive. All in all, just want some advice please❤️
