What were some the earlier signs of OCD that you experienced that you didn't know was OCD?

So maybe the title wasn't the best to to put it but when you guys start having obsessive thoughts how do you stop them before it turns into compulsions and anxiety?

Hi, I’m new to this app and newly diagnosed. Question for you all, What things did you normalize and do without a second thought that when diagnosed, you realized was actually your OCD? Mine was how concerned with germs I am. I hold my breath when I open a door so the rush of wind doesn’t infect my lungs from whatever is in the room. I thought everyone was really careful and concerned like me. But Ive learned it’s not normal the lengths I go to. What was yours?

So basically I didn’t know till my hocd started. But looking back at my life I had ocd since I was a kid. Like 6-7 years old. First time happening I remember that when I was doing stuff many times I had to say something like a little poem in my head to stop it. Then I had this thing were if I felt my left foot touch the floor 5 times I had to do the touch the floor with my right foot too. Then I had something I guess contamination??? Basically after washing my hands I had a sensation on my hand like I could still “feel” the germs and I had to wash them again. Then I started having thoughts of my family members getting hurt. I had intrusive thoughts about me hurting my dog. Then I had this obsession that a guy who used to be in my school is looking for me to beat me up. And how it’s this obsession about my sexuality even tho I never doubted or questioned it before. Is that possible??? Like can you be born with it? I’m pretty sure both my parents have it too. At least at some level. Take my father for example he had an obsession that he was going to die the moment he turned 30.
