hello, i have came off the implant 6weeks ago, 3weeks later i had a very light period (brown/pink) lasted 1day and a half. I have had cramping, tired but cant sleep at night, heartburn, felt like my heartrate was faster for a week. I also have lower backache, almost throbbing on the left handside (left is also where most of my tummy cramps are) i feel thirstier too. Neg home pregnancy test
