Constant Uterine pains & Spotting at 26w5d during 2nd pregnancy

So we spent half the day in L&D yesterday cuz I started spotting & was having a few contractions. They monitored me & Zoey & did some test. I was getting worried for our little girl, even with her moving around her hr was getting as low as 125 but they still sent us home anyways, I guess 125 ain't low enough for an active baby. By 9pm last night I started spotting again & I've been having pretty much non stop uterine pains. The only time I get relief is if I'm asleep but I kinda can't do that all the time when I have my wonderful 9, almost 10, month old boy to look after. Anybody have any suggestions besides taking Tylenol & resting? Tylenol doesn't help & like I said I have my boy to look after so there is hardly any resting that I can do. I'm currently 26weeks5days pregnant.
