Had period but still feel pregnant.

Ok. My periods have always been a few days off here and there. Last month I started feeling like I might be pregnant and my period was late. The first few days weren't a big deal since I've been late before. On the 9th day I took a test...negative. I waited and took another one on the 11th day...negative. My friend told me on the 12th day to try peeing in a cup and taking a test since I just pee'd on the test the last 2 times, so I tried that...negative. I started my period on the 14th day. I was miserable. The first 2 days of my period were horrible. The cramps were almost unbearable..........

So ok, I had my period, regular flow, for 5 days (normal). Well, as soon as the period stopped, a clear, slimy discharge started. It has been 2 weeks since my period and I'm still having the discharge, although it has gotten a little bit lighter. There is no bad smell with it, no itching or discomfort. I still feel like I'm pregnant. I haven't taken a test since I obviously had my period but I was wondering if anyone else experienced a situation like this and ended up pregnant. I'm exhausted most of the time which is very unusual. My breasts are killing me, which they have been since I started my period (very unusual for me to have sore breasts after the first 2 days of period and it's been 3 weeks). And I seem to be having a lot of heartburn. I realize it's unlikely for me to be pregnant, but I was curious. Any response would be great. Thanks.
