I had sex 17 days ago. 2 months ago I did an egg donation and the hormones really took a toll on my body and my birth control wasn't helping. 3 days ago I stopped taking my birth control all together to get my period started (1 week before the sugar pill week). Do I need to worry about pregnancy even though the last time I had sex was 17 days ago? All the tests are negative.
There is still a possibility for pregnancy if you haven't had your menstrual cycle yet. You may want to get a urine or blood pregnancy test from a doctor to double check. Also, you should see an OBGYN doctor, who is more specialized in this topic.
