Hi all, I am after some advice , if anyone can help that would be lovely. I have been diagnosed with Pcos and and have been taking aldactone, Yasmin and Minocycline for the past 8 months. I have chosen not to withdrawal been for about 4 months. That past 4 weeks I have had constant abnormal discharge. this first week was black old blood that was thick and dry and I was constantly discharging it. I then bleed for about 4-5 days. Then it stopped and there was no blood or discharge for a couple of days. And since then it has been constant discharge which is a mixture of long stringy black discharge which is about 5 -6 cms in length and I literally have to pull it out of lady parts when I wipe. I also have thick dry black discharge. I am under an endocrinologist and I am on a waiting list to get back in for an appt. If anyone had any idea about this kind of discharge it would be greatly appreciated. Thanks!
