So, I had my first sexual intercourse ever last February, 1. We did it with protection, a condom. He didn't even put that much into me, just the tip of it, and also took it out a long time before he actually came. We made sure the condom wasn't broken by filling it with water, after the relation. It wasn't. So, that was the only time we did it. After that, we went through many masturbation experiences, on which he ejaculated. It happens that my period is very irregular, and I have no idea when my ovulation is supposed to happen. My last period was by the middle of January, more or less. After that sexual intercourse, I had some transparent discharges, but nothing with too much intensity. I assumed that would be a sign of the ovulation. Until today. I woke up and felt a large discharge, and instantly thought it should be my period. For my surprise, it was just a transparent big discharge of mucus, the egg white type one, very elastic and in a large amount. But later, there was a little blood discharge, a light one. Then, it left with a caramel-color mucus and, by the night, I saw a thing that just reminded of blood vessels, when I went to the toilet, and it had a real blood color. My question is: 17 days after the sexual intercourse, is there a possibility this little blood discharge, or spotting, is related to a possible pregnancy?
