Late or skipped period ?

Marie

Ok so wierd thing my period is 4 days late off the calendar ,usually comes on time or a day before ..my last period was Jan 25 ,5 days length every 28 days .. I haven’t had sex in a couple months ,definitely not prego ,plus took a test ,this month I haven’t really had pms symptoms like I normally do ,I’m very tuned in with my body ,no stress at all ,I’ve actually been doin just fine ..I remember throughout a few years my cycle would come a few days late bc of stress that I know of bc I knew I was .. I’m wondering will it skip this month bc it’s only 28 days and then have 2 the next or a normal ??im freakin confused bc this never happened ,I don’t feel like I’m gettin a period this month ,but this never happened ,I’ve been off of nuvaring for 8 months ,and I’m barely sexually active bc my bd is in the military ..so idk what it is ,any ladies wanna give me some advice or can relate 🤦🏽‍♀️😕
