Period cramps

shay
So I know they say real contractions feel like period cramps well that's how I feel right now but it doesn't exactly feel like contractions it feels like my period is trying to come or like if I was on my period when blood clots pass through... I passed my mucus plug last night and been having the cramps ever since is this a sign of labor ??... I'm not bleeding or anything just cramping and baby is very much active.. I've never actually been through real labor since I was induced with my first child
