I had my implant removed on the 25th March so 4 weeks ago. Ive had some spotting on 13th and 15th, only when wiping and the tiniest amount also a few cramps. Weve had unprotected sex on the 4th,5th,9th,10th,13th,20th and 22nd. I've done a test and its negative so could this just be my body taking it's time to adjust?
