34wks with menstrual like cramping

I’m currently 34wks+5days and this past Monday I had my biweekly appointment.i had the strep b test done and immediately felt some discomfort during the swab.later that night I started getting light cramping,which has been the case for the following days.before I had taken the test I wasn’t getting any cramping at all.since yesterday I’ve been having basically all of the symptoms I normally get when I’m on my period.cramping and pain rushing down my legs to my feet (Water Retention).yes I know I’m 34wks and cramping I guess is normal as well as the water retention.but I woke up with severe cramps,should that be normal? There not light cramps anymore
