Having a rough couple of days 😞

I'm 20 weeks pregnant & as of Monday I started having fairly strong cramping in my lower abdomen, I've never encountered this so I called my dr and she told me to take it easy, drink lots of H2o and relax....Tuesday I woke up feeling awful, pelvic pain, cramping, dr ordered me a test for A UTI, came back positive..this is my 2nd one in a month. Has anybody experienced multiple uti's during pregnancy. Today, I've been on my antibiotics for about 24 hours and I've got a fever, chills, no appetite and just over all feel crumby! I called after hour line but dr said to call in morning if still feeling this way! ☹️☹️☹️
