On Birth Control: I often advise people like you to take a step back and read out loud your question. You are on birth control yet you did a pregnancy test? The reason one goes on birth control is so that they have less unnecessary worrying. To get pregnant, as I am sure you know, you have to be ovulating and you have to be exposed to fresh semen. He did not ejaculate inside of you. Why are you worked up? ...Read more

Had unprotected sex about 2 weeks ago on  last day of cycle. My next cycle is next week wed. But now I have a light brownish spotting&  hpt negative?

How to get Pregnant?: Let me try to interpret this scenario. I presume by cycle you mean the last day of your period. Correct? In medicine we count the first day of your period the first day of a cycle and the last day before your next period would be the last day of the cycle. So, to get a valid answer here is what we need: on what day in a cycle do you ovulate? How long are your cycles? Was the last period abnormal? ...Read more

However, you are not protected against STDs and you do need to be concerned about them. Implanon does very frequently cause disruption of regular periods. ...Read more
