Spotting and cramps be aware

So I went in for a uti , but I knew it was that or a yeast. Two days later had spotting I mean like the size of a quarter when I wiped it happened 3 times and I had period cramps. I’m 31 weeks honestly I thought it was the uti so I went to the er. They sent me to labor and delivery. Guess what I was having contractions 3-4 mins apart. The good thing is my crrvix never open. They stoped it kept me for a few days don’t know the cause and got me on bed rest. Laddies just be ware this is my 4th kid. I know ftm freak out but it don’t matter what number kid if ur body is different go it’s not going to hurt . Those cramps were contractions and I would have never thought. If I wasn’t drinking double the water and double bathroom breaks I would have never notice. I only looked at the tissue to make sure my uti wasn’t something else . So just want you laddies to know me and baby are good I know she is still tryna come early but at least I got all the shots and more knowledge to know what to expect if she does.
