TTC, overthinking, prayers

I had recently tried to conceive last month on the 21st, my ovulating day, and I’m a little nervous. One week has passed. I’m just waiting for this week to be over to see if I get my cycle this week, and if not, I want to try to get a pregnancy test! But I’m a little afraid it would come out negative, and I’m going to be so sad.
I have been thinking about it ever since we tried to conceive on my ovulating day: “What if I’m not pregnant?” “What if I get a negative?” Honestly, I just need a boost of encouragement. Do y’all think it’s possible I could be pregnant?
