My last period was around September 5th and I have consistent periods around 30 days apart. I had unprotected sex twice on the morning of September 21st. I then had my Styla IUD removed on the morning of the 22nd. On the 24th I had brown spotting, cramps and was ovulating. This only lasted about 1 day. It is now the 30th and I’m having lower back pain, light cramps, and brown spotting again. I don’t normally have cramps during my periods. I figured the first brown spotting was either ovulation discharge or caused by the IUD removal. Now that I’m having it a second time I’m wondering if I’m having implantation discharge. Any help would be greatly appreciated!
