Contraception whilst taking tamoxifen?

Hello
I was diagnosed with breast cancer this year, at 33, and was told to stop taking the pill. After my treatement and radiotherapy, I’ve started taking tamoxifen. I’ve been told that you shouldn’t get pregnant whilst taking Tamoxifen, so I’ve been exploring other contraceptions… I’ve been using the natural cycles ap, which monitors body tempature etc and predicts ovulation, etc, but because my periods are becoming less frequent and irregular, I’m not sure if this is effective for me? I wondered if anyone had any experience with this? Also, any advise on other contraceptives which i can take which are non hormonal?
Thank you

I had a coil put in, it was fine. Not the one that releases hormones though. Best wishes.

Hi jocelynb09,

Thanks for posting.

It can be difficult to know what contraceptive options are appropriate following a diagnosis of breast cancer, particularly as you were previously on the pill.

It’s not uncommon for women who are still having regular periods to find that their periods change whilst taking tamoxifen. They may be lighter, irregular or they may stop altogether. It’s possible to become pregnant while taking tamoxifen even if your periods have become irregular or stop, and taking tamoxifen while pregnant may be harmful to a developing baby.

There are a number of barrier and non-hormonal contraception methods. These include condoms, Femidoms or a diaphragm. As @edp has mentioned, it may also be possible to use the non-hormonal coil (IUD or intrauterine device). We would always suggest you discuss the most suitable option for your individual circumstance, with your GP or treatment team.

We offer support tailored specifically for younger women with primary breast cancer who are aged between 20-45 years. This includes our Younger Women Together events that are run face to face and online. This support offers the opportunity to meet and share experiences with other younger women and get expert information in a confidential space. More information can be found on the links above.

Some people find talking with another younger woman who’s been diagnosed with breast cancer helpful. Our Someone Like Me service can match you with a trained volunteer who’s had a similar experience to you. They’ll contact you by phone call or email to answer your questions, offer support or simply listen. You can ring the Someone Like Me team on 0800 138 6551 or email them at someone.likeme@breastcancernow.org so they can then match you to your volunteer.
