Unprotected sex in fertility window

Jodie

Hi had sex on Saturday at 1:30am (BF came inside me) fertility said 13% on the app and again that night at like 11:30pm again 13% on the app (BF didn't cum inside me but on boob's, sorry for the to much info)

We haven't been on any contraceptive for 2 Years but my periods only came back in Feb this year. We aren't "trying" to have a baby but if it happens we would be pleased, we have been together 7 years but ideally wanted to wait until we had bought a house.

I have wanted a baby for a while so part of me is hoping it will happen... What about anyone else how successful have they been at getting pregnant?
