So here are the details of my situation that I am hoping for someone to shed light on. So my period was from the 18th of December, 2014 to the 25th of December, 2014. On the 28th of December at 8:30 my partner and I had sex. (It was the first time ever for either of us). I was not on any form of birth control but we did use a condom. Since he was fairly nervous becoming erect was difficult but eventually he did. Now he didn't fully ejaculate inside of me but we believe he might have a little bit (and the condom had broken). So not wanting to take any chances at about 10:39pm that same night we were able to make it to the drug store and picked up plan-b (two tablets). I took both at once.
Then all was fine for the next few days until the 2nd of January when I began experiencing bleeding (it was a brown discharge), then over the course of the next few days it turned into a darker red and an actual flow. Then it died off and lightened. The bleeding lasted until the 5th with the 4th and the 5th being lighter in flow.
Now here is the issue. It is now the 22nd of January and I still have not had my period. I do not have sore breast, dizziness, nauseousness or any of the other symptoms related to both plan b or pregnancy. I am just wondering what exactly is going on. I know it's hard to say for certain but what are the changes that I am pregnant? When would be a good time to expect my next period? It's four days late than normal. Any and all advice would be greatly appreciated!
Thank you! :)
