Researchers are collecting safety information on a new combined oral contraceptive pill. The study is observational — meaning no treatment is given and nothing about your care changes. Your doctor has already prescribed the pill; this study simply runs alongside that.
If you're interested in taking part, click below to answer a few questions and find out if you're eligible.
You may be eligible to take part if you:

Are aged 18 or over

Have been prescribed and started taking one of the following pills in the last 30 days:
Nextstellis (drospirenone/estetrol)
Yaz, Yasmin, or a generic containing drospirenone/ethinylestradiol
Another combined oral contraceptive containing a progestogen and ethinylestradiol

Have not used a combined oral contraceptive in the two months before your current prescription

If you take part, you'll complete five short online questionnaires over two years — each takes around 10 minutes and can be done on your phone, tablet, or computer.




Occasionally, if a questionnaire flags a health concern, the study team may follow up to request supporting information from you or your doctor.
Compensation
You'll receive a $20 online gift card for each questionnaire you complete — up to $100 in total. Please allow around 6 weeks for gift card processing.
