I usually have normal,regular periods. I've only been late 3 days once, which made my period come on the 17th, it's been regular since then. I had unprotected sex the 5th,12th,and 19th. I believe I might have ovulated on the 5th. I'm now 4 days late. I have small cramps that only last for a minute, a few left side pains, a bit more tired, a bit of back pain at work. I don't feel stressed at work, or if it could be cause I've been sick for about 2 weeks. I took a pregnancy test on the day after and it came up negative.Yesterday, I cramped a tiny bit and there was a tiny bit of light colored blood that was barely there. I wouldn't have noticed if I didn't check my cervix which is still low and open. It only lasted for a minute then went away. My breast have started to hurt if treated rough, and sometimes I feel like have acid reflux, where a bit comes up but I feel like throwing up more but can't. I've been a bit emotional, where a Disney movie almost made me burst into tears, and I started crying out of nowhere because my boyfriend didn't say good morning back. 
Pms or possible pregnancy?
