Stressed a little please read 27 weeks pregnant

So I’m a little stressed I’m 27 and 3 weeks I’ve been having these really bad cramps and I half to run to push like on the toilet because that’s what relieves them and my breast have been dumping out milk. Well today I went to my appointment and tested positive for FFN again!! So then decided to check my cervix and I was already 50 percent effaced and a finger tip dialated I’m a first time mom (and a young mom) so this was all crazy to me because the midwifes were all checking me at once Hah but ya now I’m now on bed rest sadly and they are going to start giving me shots to Develop her lungs faster so I’m hoping she stays in till her due date!!
