On november 28 I lost my virginity and the condom broke, that same day I took plan b. I got what I thought was my period on December 21 though it was very light, lighter than usual to the point that there was no need of a pad nor pantyliner. This very light bleeding lasted till the 22. I thought that those were just the effects of plan b and let it be. Though I did take a pregnancy test on December 11 and the 12 and both came out negative. Now in January I was supposed to have my period on the 19 and I still haven't gotten it nor gotten any symptom that I will(bloating or anything). I'm not sure if this is because of the plan b pill or if I should really take another test. Please let me know any advice or information you guys may have, thank you so much!
