Confused?

This is my first post, kinda nervous! Anyways after I went off birth control (2 years ago) my periods have been fairly short, my husband and I started trying in oct. And have only been ttc for the last two months. But the weird thing is starting in nov my period was only like 3 days same for dec jan and feb and this last month was only 2 maybe 3 days. I've been breaking out like crazy and I never break out also always feeling like I need a nap! Just kinda curious if it's normal to have a 2-3 day period
