CM/Discharge question possibly TMI

Beth
Hello all I have been TTC for almost 2 years. I have an 8 year old son. No ideas as to why I'm not getting pregnant all tests have been normal. I had a mild blockage that gave way during my HSG test last month. I'm currently 11dpo AF due on the 12th. About 6dpo I start having strong cramps lasting two days, a few headaches no other symptoms. Then about 9dpo I had the absolute strangest discharge I have ever seen. It was Clear but solid like gel or silicone. It was not egg white cervical mucus, I know what that looks like after 14 months this was something completely new on me. Anyone have any similar experiences or insights?
