Received a positive fFN test was tests due to leaking fluid, I've heard this test has a high false positive rate. The nurse called and I explained to her I had menstrual like cramps, back pain, a lot of pelvic pressure and tightening in my belly constantly. Well the nurse gave me a call back and told me to go to the hospital to get my first round of steroid shots. I have an appt today I guess we'll see what my doctor says 😳
