Swear I've been at the beginning of labor for 2 days

Whitney

So I've had lots of BH contractions recently and and then a few episodes of some real feeling contractions but not regulated or got stronger. Well starting yesterday evening, I started having contractions that were anywhere from 3 minutes to almost 45 minutes apart and haven't stopped since but they haven't gotten stronger or regulated at all. My question is.. how long can contractions last without getting stronger? This is crazy and not at all how my labor went with my first born. Someone tell me I'm not alone. I don't want to go in because I know they'll send me he since they aren't getting closer together or anything.
