Finally TTC!

So my husband and I are TTC after almost 8 years! We have a daughter who turns 8 in December. I am so excited. He’s a man and he wants a kid so he’s into it lol so today was our first time really trying and after I laid down for maybe like 5 minutes(maybe a little less). I walked to the kitchen then came a laid back down. Did i decrease my chances by standing up?? I know it might be a dumb question but our first daughter was a big surprise considering we were only 16. Any other tips would be helpful as well!
