I’m really suffering with this. I see no end :(

Period/ Pregnancy OCD. And like False memory OCD? Has me checking every interaction I have with men. Even ones who aren’t my partner. And are just my friends. A friend of mine is staying over at our place for the weekend. Turned up late. My partner didn’t want to have a yap as it was late but I decided to go say Hi. And we talked for a bit on the couch. Then I went to bed because I had nothing left to say. And it’s like almost 1 am. My brain is now worried that because no one was with me. It can be misconstrued. That no one can reassure me that what I know to have happened is what really happened. I know we just sat on the couch and talked about DND and the shows we watched. It literally just happened like not even an hour ago. Then I grabbed a drink and went to bed. And I know when my period is inevitably late again this month that I will remember this moment and my mind will change it to suit the narrative as it’s done every month with any interaction with men I have that isn’t my partner. And even though I know this happens. I believe it all the same, all the time. And now I’m kicking myself for giving my OCD ammo. Like I don’t have enough to worry about, Why did I have to go talk to him. Could it not have waited till morning. I should have just ignored him and went back to bed. I can’t sleep now. My stomach is dropped and I want to cry. I even wrote myself a reminder in my notes to say exactly what I did tonight so my OCD can’t change it. But that’s a compulsion I think. And I’m just making it worse. I can’t sleep. I feel so gross. That my mind is convincing me Im capable of doing such things with a friend of mine that I genuinely see as a brother. And that it’s trying to convince me every month I have somehow cheated on my partner with any man I have even spoken too. Last monthly cycle was hell. And my period was the latest it’s ever been that time. I’m so scared for this one coming :(
