Suddenly I feel like my thoughts are stronger and I'm losing tolerance, is this a so-called relapse?

anyone else have a good evening/ day then fall back down hurrendously the next day? Honestly yesterday I felt great! Like I knew what I like (opposite gender) and these ‘false attractions’ are just false alarms caused by OCD… like I knew these thoughts and feeling are OCD. Today I question it all over again. Are these false attractions real? Why has my loss of opposite attraction feel like it won’t return? Though yesterday I got snippets.

I'm 20 weeks pregnant, have suffered with ocd since 16. Had a mental break down over a year ago. Here I am feeling like I am relapsing and the thoughts are out of control, and even worse now that I feel guilty I am causing my baby stress when it's not his fault.

today again...erp and a strong feeling that it somehow arousel me and creates adrenaline, and the longer I expose myself to the thoughts, the more wild and detailed the images in my head become, accompanied by the feeling that I like reality as well...
