Eureka! I have connected the dots. I was wondering why I suddenly got my period after months of not having it. Then I remembered my dr telling me I had high prolactin. THEN I remembered the last time I had high prolactin I didn’t get my period for a year. And I realized I stopped haldol about a month ago. So, out of curiosity, I googled prolactin and haldol. Apparently, haldol is the most likely of the typical APs to cause high prolactin! So in my non medical opinion, this is why I’m getting my period again. I bet my prolactin is going down.

So yes, I think I figured it out.
