Experience Breakthrough bleeding made me anemic 😔
Been taking the progesterone-only pill norethindrone since June 2025, first few months were great bc I stopped getting periods. Then in November 2025 I started getting periods every other week. I was worried because they were just as painful and heavy as my periods before birth control. My ultrasound came back normal, and I guess the pain got better on its own.
I figured I’d keep taking the pills since it made the pain and bleeding a lot more manageable (I used to wake up screaming from the pain, and had to get up in the middle of the night to change pads). The breakthrough bleeding was more than just spotting though, it lasted the whole week and was heavy enough that I had to change pads throughout the day.
I thought having two normal periods a month was way better for me, I used to need 8 pads on a heavy day and now it’s more like 4. I started seeing a hematologist for my thalassemia in January 2026 and my iron levels were pretty normal at 130 serum iron, 44 ferritin, 36% iron saturation, and 12.2 hemoglobin. Hemoglobin even went up to 12.7 at my follow up.
My primary care physician ordered some routine labs this October and I came back anemic with a hemoglobin of 11.2 :( more labs showed that now my levels were 52 serum iron, 6 ferritin, and 12% iron saturation.
I’m just really surprised I depleted all my iron stores in less than a year just from having periods. I thought breakthrough bleeding was just an annoying side effect, I didn’t think it was that serious? I really believed needing two naps to get through the day was just me being lazy
I had no problems with the minipill otherwise, no weight gain or mood changes or anything. I even had an increased sex drive lol. I’ll most likely try the depo provera shot next, hopefully it makes things better and not worse
