I can't quite pinpoint why, but straight after my period ends I get the most intrusive thoughts, become self critical, insecure and over analyse everything. It is affecting my relationship with my bf. I have been with him for a year now and once a month, like clockwork I get insecure and judgy and doubt the relationship and get relationship anxiety to the point of wanting to end things with him- it affects my sleep which worsens things. I get irritated easily and have anxiety attacks frequently. It's not PMS, because it happens when I am ovulating- I hate it. Anyone else have the same?
