Help, I'm only 32+3 with my second, could I be in early labour???

Va

I've been having braxton hicks contractions since 17 weeks, they were never painful, just my stomach gets super tight and today, like 30 minutes ago I've been getting them every 4-5 minutes now, but it's not painful, just my belly gets very very tight. My husband is away for few drinks with his family and friends and I'm meeting them all later on, should I be worried?
