Trying to get pregnant

Carol • Wanting a baby for almost a year now been trying ever since our first one is in heaven playing with cars 🙏🏻😘💙.
Ladies I need your help how can I know if I'm ovulating 
What test can I take to know I can conceive
I went to the doctors all 
she told me to keep trying every week or even everyday I have sex every 
weekend because during the week 
we are both tired I want to see what options I have and what test can I do at home to know when I can have sex and get pregnant
