Preterm labor

Mrs • I`m 33 w/3 daughters & a 1 son.. I have been w/my husband 15 yrs, but only been married 5 yrs

Anyone ever experienced it? I did earlier today. Dr told me I was having Braxton Hicks but sent me to labor & delivery. Got there was hooked up to the monitor & sure enough I was contractions and had to get a shot to stop them 🤦🏽‍♀️ 32 weeks 3 days
