Is spotting on mixed hormone birth control normal?
Combined oral contraceptive pill
Nausea, vomiting, headache, bloating, breast tenderness, swelling of the ankles/feet (fluid retention), or weight change may occur. Vaginal bleeding between periods (spotting) or missed/irregular periods may occur, especially during the first few months of use.[52]
Emergency contraception
Emergency contraception has not been shown to affected the rates of abortion within a country.
Emergency contraceptive pills (ECPs) (sometimes referred to as emergency hormonal contraception, EHC) may contain higher doses of the same hormones (estrogens, progestins, or both) found in regular combined oral contraceptive pills. Taken after unprotected sexual intercourse or contraceptive failure, such higher doses may prevent pregnancy from occurring.
