Contractions earlier followed by cramping

Earlier tonight after i was done with work my fiance, daughter, and i had gone to go for a walk by the pier. While walking i started having some moderately painful contractions on and off but they stopped within an hours time. Now im sitting at home and im cramping pretty bad... should i be worried? Its probably stupid but im only 33 weeks and not sure. My labor didnt start by itself with my daughter, i was induced, so im not sure what to watch for. I lost my mucus plug a while ago but it wasnt bloody at all so i know that doesnt mean much. 😬 idk
