Preterm ?

I’m 33+4 today , yesterday I was in L&D for mild contractions and lots of pressure, they hooked me up and they were consistent and her heart was dripping with every one , they decided to do an ultrasound and she right on my cervix with her head , the contractions slowed and they sent me home and I’m home from work today had more while making my daughter breakfast , but last night I was woken up by awful diarrhea (tmi sorry) I’m worried my baby will try to make her appearance way too early 😞 my second baby girl and i have nothing ready for her yet :/ my first was overdue so my baby shower is on the 14th and I’m due oct 4th. Ugh
