Lamictal

I was hoping to get some advice concerning Lamictal. I have been diagnosed with bipolar 2 around two years ago now and I’ve been on it ever since. Well, normally my brain used to work quick. I still have friends who tell me it’s exceptionally fast, but not to me. I found a new more challenging position at work and my brain isn’t up to par anymore. I feel like I just can’t function like this. My brain is too slow and doesn’t retain any information. My nurse practitioner mentioned that’s always the trade off: less mood swings for a slower brain which I don’t find fair at all. Now I am 9 weeks pregnant and have been wondering if I can stop my meds. With preggo brain to top it off it sucks. Has anyone had experience either stopping their meds or stopping them while pregnant?
