Trying to stay positive when TTC

So my wife and I have been TTC for a few months now. We had our first insemination last month on August 24th. After insemination (well days after of course) I was so sure I was pregnant! I felt so many symptoms and I just knew I was pregnant. We took a pregnancy test (it was honestly earlier then we should have, but we’re so excited!) and it turned out to be negative. We were pretty bummed, but decided to test again when the day of missed period arrived. Unfortunately my period did start and as it turned out I’m not pregnant. We have another insemination appointment this month on the 15th, but I’m so nervous. I’m worried it won’t take again. Does anyone have any words of advice to stay positive? Thanks for listening!
