I am a 32 yr old who has been trying to get pregnant for over a year since I got married. My periods are usually regular and my cycle lasts 26 days. On cycle day 18 for the past few years, I have noticed a large volume mucusy discharge with blood streaks, sometimes overall pinkish in nature. It often happens about 4 days post ovulation (by OPK's) and I use it as a signal for my pending period in one week. Pregnancy tests have been (-) through out.
After telling my doc, underwent an u/s that showed some fluid filled tubular structure but it did not look like my fallopian tube or ovary. Will go for repeat before my period next week.

Has anyone experienced this?

Thanks,
