Trying to conceive

My husband and I decided that we want to start a family and my period was about ten days late last month so I'm a little unsure of when I'm ovulating... I'm really wanting to do all that I can so that we have the best time while trying and also have the best opportunity to get pregnant. So I was hoping for advice and maybe just helping words, I dont want to stress too much and I'm already taking prenatal vitamins. My cycle is usually 30-32 days, but like I said, last month I was 10 days late. Any advice is helpful, thanks!!
