I NEED SOME HELP!

I am dating a guy I’m utterly in love with last year we lost a baby and We have been trying ever since he deployed and was gone and has been back 3 weeks we live together we have sex almost everyday if not just everyday a couple times a day. We are super sexually active yesterday I took a ovulation test (first time for me) & got the solid smiley face I was super thrilled I don’t know lately my anxiety has been high and I overthink a lot so immediately I’m watching videos of the great sperm race lol how babies are conceived I have a 4 year old from my last relationship and I wasn’t this anxious or almost annoying as before. He asked me why I’m making it so weird and why we just can’t chill and let nature take its course. I’m really scared of losing another baby or not being fertile enough to carry his child idk I’m really scared I kinda feel alone does anyone go through stuff like this
