Does anyone else have moments where it feels like another theme could potentially pop up but then it doesn't grab hold like your main themes?

I’ve had different themes of ocd throughout my life. Can they all differ such as how the thoughts may present? Currently my thoughts feel so true immediately (like they genuinely feel like what I think) but in the last theme I feel like it may have been more of a “what if I think this” type of situation

my OCD is doing what it does best and it’s randomly selecting themes. Once I’m not scared or react to one it bounces to another. And then i temporarily forget all of my coping skills for that theme. Rn it’s fixating on the time I had a panic attack and it’s trying to make me have one again

Themes constantly switching. I’ve been suffering with real event ocd the last year and am currently in therapy treating it. it’s nowhere near as bad as it was last year and it’s felt like a nice break. there’s days where it gets bad but i can’t compare it to the stress of last year. However i’ve noticed every time i overcome a theme a new one hits me out of nowhere. i’ve suffered with ocd since i was 9, and ive had multiple themes. i’m in a 2 year relationship with my partner and it’s amazing. she’s probably my second proper relationship due to the fact my first relationship gave me so much fear to get into another one as i was cheated on, and needed a few years to get over that. i kind of guessed that ROCD would creep in at some point as it just felt inevitable. anyways, i know my partner is not cheating on me, she’s beyond loyal, we are so so in love but i think due to that first relationship i had, being cheated on really messed with my head. it’s like my brain is telling me my partner has someone else even though i know in my heart nothings going on, and i trust her with my life. i also think because im in the happiest relationship of my life, anything that would indicate loosing her makes me feel sick and riddled with anxiety. and i know that’s completely normal for everyone. i think the most frustrating thing is, is knowing that my OCD has finally crept into my relationship which is something i never wanted it to do. this is a brand new theme and i have no idea how to treat this. i will speak to my therapist but if anyone has been through this theme and any advice in the meantime i would really appreciate it :).
