TTC is getting me down

Deedles • 🇦🇺 Finally got my BFP!!! 🤞🏼 due December 2019 💕🤰🏼
Does anyone else every month feel that no matter how hard they try, no matter if you BD every day of your fertile period, every second day, a monthly marathon, whether you use preseed, do OPKs, take your BBT, watch what you eat etc etc and still every month you just have a gut feeling it didn't work? I'm trying to stay positive and not stress but I just can't shake this feeling that it's not in the cards for me. Seems stupid I know, but everyone around me seems to Cough and get pregnant and I've been trying to do everything right for over a year and still nothing. I know that if its meant to be it'll be I just can't help but every month pre planing my next months ovulation because I just know it didn't work. And sure enough BFNs. I'm the last of my friends without kids and I'm tired of being Aunty, I want to be mum.
Please tell me I'm not alone!!!!
