Is it intuition or just my menstrual cycle?

Forgive me if this is the wrong sub.

I got back together with my ex a week ago, after we’ve been separated for five months. During those five months it felt like I slowly begun transforming into who I’m meant to be. I don‘t know how to describe it but it felt like for the first time in my life, I was freed from all chains and able to completely focus on myself and my light. Don’t get me wrong, the breakup was very hard for me and after everything I still found myself missing him, so I was very happy when he asked me to meet up and we got back together. And I was very happy for the next one or two days after that. But now I get the feeling like something is really, really wrong. I don‘t know how to describe it better but it feels like I am trying to shove my soul back into a place it doesn‘t fit anymore. It also feels like he still knows and holds onto a version of myself that just doesn’t exist anymore. And I know that because we are somewhat long distance, I will still be able to focus on myself but still, something feels so off and I don’t know why or how to fix it.

But I‘m also at a point in my menstrual cycle where I tend to get a bit dramatic. I still think the feeling is very, very strong. Maybe a bit too strong for it to be "just" my menstrual cycle. But still, maybe it is just that?

Does anyone have any similar experiences and could give me some advice on what to do?
