Combined Pill
A pill with estrogen + progestin
form
Daily pill
What it is
A daily pill containing both estrogen and progestin (a lab-made hormone similar to the progesterone your body makes naturally). It's one of the most studied forms of contraception, and it often does a lot more than just prevent pregnancy.
How it works
Prevents ovulation by keeping your hormone levels steady so your body doesn't release an egg. It also thickens the mucus at the entrance to the womb and thins the uterine lining, so there are two extra layers of protection.

The good stuff
- Regulates and lightens periods
- Reduces cramping and PMS
- Can significantly improve acne, especially with pills that use a skin-friendly progestin like drospirenone
- May reduce symptoms of endometriosis and PCOS
- Can be used continuously (back-to-back packs) to skip periods
- Decades of safety data, one of the most studied medications ever
The trade-offs
- Must be taken at the same time every day
- Not suitable for everyone, especially if you get migraines with aura (migraines with warning signs like flashing lights, blind spots, or tingling beforehand), smoke, or have a history of blood clots
- Takes 2–3 months to see the full effect
- Small increased blood clot risk (this varies depending on the pill type)
- The oestrogen can affect mood in some people — low mood, anxiety, or feeling flat. It's one of the most common reasons people stop, so notice how you feel in the first few months and tell your doctor if something feels off (switching the progestin often helps)
- Does not protect against STIs
- May cause nausea or breast tenderness in the first 1–2 months
Avoid if
- You have migraines with aura (migraines with warning signs like flashing lights, blind spots, or tingling beforehand)
- You smoke, especially if you're over 35
- You have a history of blood clots or stroke
- You have an inherited clotting condition like Factor V Leiden (a gene change that makes clots more likely)
- You have high blood pressure
- You're breastfeeding
