need advice!!! can't stop obsessing!!!

So I need help to stop stressing and thinking about pregnancy. I'm driving myself crazy. September I went on birth control only for that month then stopped it. October we were ttc but obviously I didn't become pregnant. I took ovulation tests everyday and never got a positive. Reason could've been because I took them with first morning pee not knowing any better or because I just didn't ovulate bc of the one month of birth control. So anyways month of October, I was fertile the 24th- 30th. I had positive ovulation tests 27th, 28th and 29th. We BD everyday in my fertile window and basically everyday of the month other than maybe one or two days. I was taking fertilaid almost everyday other than a few times I forgot. We used preseed maybe like twice. I don't understand what's going on. AF is due on the 12th so I know it's still early. But I'm literally testing everyday and getting negatives. Every single thing wrong with me, I'm thinking it's a sign of pregnancy. I just want to be at peace and let it happen when it's supposed to happen but I can't stop obsessing. I don't want to get my hopes up. How can I get my mind to stop obsessing???? Any advice??? I just want to be pregnant so bad

Disclaimer: I have one son already from a previous marriage but my current husband has no kids. I know I haven't been ttc as long as a lot of others on here, but I'm just asking for advice on how I can stop obsessing???
