I had sex during the 3rd week of July which was around the same time I started taking birth control pills for the first time. I got my period the 1st of august and decided to take a pregnancy test on the 7th and 11th and both came out negative. But throughout this week I have been getting this wierd discharge with a white yellowish color. I have never had a discharge like this before so I'm wondering what it could be? Could it be an early pregnancy symptom?
