Q. Can taking birth control pills cause milky thick vaginal discharge?

Hello doctor,

I am a 24-year-old female and I was on the birth control pill Aviane for almost two years. I never had any negative symptoms and had an overall good experience but I decided to stop taking it after ending my relationship because I would no longer be sexually active. About four weeks after my withdrawal bleed, I had my first period again and everything seemed to go right back to normal. I have been off the pill for a year now, and my periods are totally regular, but I have noticed some slight differences. Before BC, my cervical mucus seemed to change throughout the month but now it stays the exact same. Thick and milky. Occasionally, it will be a little more watery, but it used to get that egg white consistency around ovulation and such. It does not seem to do that much anymore, if at all. Although I am pretty certain I still have ovulation pain around the middle of my cycle. Should I be worried? Did BC mess up my body? Or is that not cause for concern? Everything else is completely normal. My cycle is a perfect 28 days and my periods are back to how they were before. The only difference is that I used to still have some light spotting on day five, but now it is mostly gone by day four other than a bit of light spotting. I am not trying to conceive, but I was wondering if this was something I should be worried about. Thanks in advance.

Welcome to icliniq.com.

Firstly, birth control pills do not have this kind of lasting effect which might be over or after a year, so the change in discharge is not because of pills. Secondly, changes in consistency of vaginal discharge over the cycle are totally normal. These changes are due to hormonal changes which are taking place in different phases of the cycle. Thirdly, if the discharge is not smelly, itchy or associated with any abdominal pain or painful voiding then it is nothing to worry about. If any of these problems arise, you have to seek expert advice then only. Another general advice is to use cotton undergarments and wash area frequently with plain water only.

Hi doctor,

Thanks for answering so quickly. So even though the cervical mucus stays pretty much the same consistency in between periods, everything is still fine? It used to go through different phases during my cycle. Now it is the same milky discharge throughout the whole month aside from when I have my period.

Yes, it is not a problem until or unless it becomes smelly or itchy or causes any abdominal pain, etc. Because there is nothing we can do to change the consistency of discharge. It is just let nature take its course.
