Hi. Currently low dose oc pills are there with very few side effects. Headache, nausea, mild weight gain, sore breasts are few. Most patients tolerate these pills well and get accustomed in 1-2 months. Serious side effects like liver disease, formation of clots can occur but are very rare. You can do pregnancy test as soon as you miss periods. In case you wanted to know about emergency post coital pill, they are high dose and have same side effects in more intensity. Also they tend to cause irregular menses and are not 100% effective in preventing pregnancy

Hello.... So many people are taking oral contraceptives. Minor side effects will be there, and some contraindications are also there.. intermenstrual spotting, nausea, breast tenderness, headaches, weight gain, mood changes, missed periods, decreased libido, vaginal discharge are the expected side effect.. One to two days after missed period you can test for pregnancy..
