So, i have PCOS, diagnosed 5-6 years ago. I don't get periods regularly, and they have been brought on only when i use birth control, or do the fertility treatment with progesterone and clomid. I recently stopped to concentrate on getting better from my mental health disorder ( it is a one year program) so i decided to get on birth control. This was FIVE months ago. I used birth control the first month, stopped it and got my period as expected. i then stopped using the patch because i have always been unable to get pregnant, and dont get a period on my own. Now, i just had 4 days of very very light brownish pinkish spotting, no red, no clotting and my periods are usually EXTREMELY HEAVY. ( keep in mind i havent gotten a period on my own in 3-4 years, so ive only had 5 periods in a year) No recent weight loss, or change in diet. so my question is could this be implantation bleeding? And if it is implantation bleeding when would it usually show up on a test after the last day i bled? ( i bled for 3 days, today would be day 4 but it is so faint i think its from yesterday) and i have been having morning sickness and occasional cramps. Another question is has anyone else experienced this, even if it did not result in pregnancy? I guess i am asking if my period could finally be regulating itself? because i had lost 60 pounds in a year but stopped losing weight in march of this year. I do have an appointment tomorrow, but i am so eager to know. either way it sounds like good news, right?! :)
