I had (this was not smart on my part, & I'm aware of it.) unprotected sex I believe it was on the 8th of March. A week or so later, I had was I thought was my somewhat early period somewhere near the time of the 14th (Many new what I thought were PMS symptoms that I had never had before, VERY sore breasts, ect.) ...It's now April 5 & I'm spotting. What's going on?
