Why do my pms symptoms go away a few days before i get my period?

Gift horse's mouth?: Consider it a nice thing that they do - most women don't like them. Some don't get any at all - that's very nice. Some only from time to time or different ones. It's not necessary, it's just a sensitivity to hormonal changes. The changes are still happening - you may just become less reactive. I believe it's fine. Ask your OBGYN if you wish.
