Could use some comfort

Here’s my calendar last month into this month. My fertile week was awful. My SO worked all week so we barely could try and BD. He only came in me once which was the 22nd. I got a positive opk the 21st so i knew I was ovulating but I didn’t take any before that so I could’ve ovulated earlier. The other day in my fertile week we had sex he came on me down there not in me -.- anyways, i have a FRER and I want to eventually test but I just know it’ll be negative. I feel like I barely could make it work this last month. Do I still have at least the smallest chance? He came in me the 12-14th but I doubt the swimmers stuck around for ovulation. I just hate that sex is needed to make a baby sometimes lol..
