Stress test 34 weeks steroid shot and bad heart reading 😫😩

I went for a stress test and a sonogram today because last week they told me the cord was wrapped around my little mans neck twice. So during the stress test they had some concerns because his heart went as low as 95. They kept me there for about 4 hours monitoring him and they gave me steroid shot today and will be giving me another one tomorrow just incase he has to come early. They also told me I am 2cm dilated and 40% effaced. Now what I am worried about is how would I know since they sent me home if his heart rate drops. Or if something is wrong? All they told me to do is count kicks they keep telling me that every time they send me home. Literally every time I go for a appointment they tell me some new bad news. I am just worried. I do the kick count but how bout while I am asleep? How would I know if something were to happen? And since I am 2cms dilated and 40% effaced does this mean he is deff gonna come early? Or I could stay this way till full term? And they did a cervix exam and when I got home and went to the bathroom there was like brownish discharge that is normal right? And another question since I am dialating already does that mean my mucus plug came out already? I been having a lot of discharge (sorry for the tmi) but I googled what the muscus plug looks like and that’s not what I’ve been having. Just normal white discharge. Nothing clear or thick like I seen the pictures online. This is my second pregnancy but I never seen the mucus plug with my daughter and I literally had no complications at all with her. I went to 40w1d with her and everything just went so perfect. This time everything just seems to be so nerve racking and I am always worried. I know them giving me that steroid shot was like a just incase and will only be good for my little man but I really can’t help but worry. Is everything ok? Is his heart ok? Am I gonna have him early and him be in the NICU? Is my baby gonna have to stay at the hospital and I leave? I know I am probably just driving myself crazy but every time I go and they tell me something new then send me home I literally go google crazy and if I don’t feel like for an hour or more I get worried! So any input or advise or any of ur experiences with similar situations will really help. Thanks ladies! Sorry I know I am rambling 😩
