Excited! Couple questions

Okay so I just want to start off by saying you guys are amazing!!! You have been so helpful! My husband and I are going on our third month of TTC. I went off my BC pill that I was in for 16 years so I figured it would take a little but I know this can help with figuring out when I’m ovulating! I was told about Pre Mom and they sent me a couple for 50% off the kit so I just got it off amazing today!!!! Any tips or advice? What CD should I start taking the strips? I’m on day three of my period right now so cycle day 3. Also what time of the day do you test. I would test each day the same time right?
