To Try or Not to Try

Me and my boyfriend have been together just shy of a year. We’re both 31 and professionals. Last month we had a chemical pregnancy and ever since I’ve been fixated on wanting to have babies. He was super excited about the pregnancy and very supportive but after I lost the pregnancy He asked me if going forward if we wanted to be careful or not. We talked about BC pill as an option but decided we didn’t want to go that route. For now we’re just pulling out. I know it’s just wishful thinking but we had had sex 4 times in my fertile window right before ovulating. I’m hoping there is a chance I’ll convince even tho I know it’s not likely. Has anyone conceived from pull out/precum? Please feed into my delusion 😜😵‍💫
