You will have to have a missed period first off and then you go from there.. hope this answers you question
It sounds like you need to wait two more weeks to test. Are you hoping to become pregnant? If you're not pregnant now and not hoping for a pregnancy right now there are some really great options for birth control that you don't have to remember every day. There are a couple of new IUDs and the Nexplanon that a lot of women really like.
