This is the CM I'm getting today - I got my IUD removed on 7/18, and started having a dark brownish/red period-like discharge, which just stopped today (I was spotting yesterday and the day before). I'm using OPKs, which have been negative since I started using them (on 7/23, I think). Can anyone help me decipher this?? I'm new to TTC, and I've never tracked my CM before! Thank you in advance :)
