Disappointed because of gbs

I’m irritated I went in to my appointment yesterday hoping they would do a membrane sweep and she told me because I had tested positive for gbs that they won’t do one 😩 I know they don’t work half the time but I had this dream that I would have it done and basically go right into labor 😂 crazy right! But now I also know that I have to be at the hospital ASAP because I need to have at least two doses of antibiotics 4hrs apart and my daughters labor lasted 5hrs total 😱
