Not sure what is happening.

Hello, everyone! This past week has been so weird for me in terms of cycle behavior, so I'm hoping to get some insight.

Last Monday I took an ovulation test, the clearblue digital that has the smiley faces. Mine came up as a blank circle, and that day I had unprotected sex with my boyfriend. Two days later, on Wednesday, I tested again and this time I had a flashing smiley. I noticed last Wednesday - Friday I had light cramping on my left side, low backaches, and sore nipples. Boyfriend and I had unprotected sex Friday - Sunday multiple times.

Since last Wednesday, I've had the flashing smiley everytime I test. What is strange is, I took a pregnancy test this past Tuesday and it came back a faint positive. However, the next day on Wednesday I was teaching my class and was suddenly hit with some pretty bad cramps. Needless to say, I started bleeding out of nowhere and had quite a few clots which is unusual for me. It was a dark pinkish/brown color. I'm not due for my AF for another 9 days.

However, I did an ovulation test Wednesday, Thursday, and today and they are still flashing smileys. I took another pregnancy test last night, but this one came back negative.

Could this have been a CP? I'm not sure what is happening.
