If you dont want to get pregnant ise contraception to prevent this happening and get you partner to wear a condom to prevent pregnancu and protect you from anu unwanted infections
Do you know you are pregnant, or are you just trying to prevent a pregnancy? If the latter, it is too late to take anything (for example, to prevent implantation). Please get advice on this sensitive issue from your doctor or counselor.
The longer you wait the less effective a pill will be. If you are pregnant and don't want to be you have 3 options 1. have an abortion (which i don't agree with). 2. Go through the pregnancy and give the child up for adoption. 3. Keep the baby (as you were responsible enough to have sex). Please carefully think about your options and how it would affect you on the future. Best of luck and please keep us updated :)
