Going to the e.r 😩

(16+4 weeks )Day three of lower back pain and now cramping again 😩 just can't catch a break I had an appointment with my ob I told her about it all and all she gave me wsd muscle relaxers and sent me home they did nothing but make me sleep .I've been cramping since 8 again and when I went to the bathroom I had some spotting not much but I'm gonna go get checked because the cramping has gotten worse I honestly don't want to go because I don't have anyone to take care of my 2 kids while they check me but I need to go figure out why I'm cramping sooo bad I want to cry I have been drinking plenty of water I'm out of ideas on what to do ....
