Am I pregnant? - i've been experiencing frequent urination, nausea, tiredness and back pain for the last week or so. I've now got my period 2 weeks early (im never early), the first day it was really light and hardly anything at all, this morning it was heavy and a brown colour, now it has gone back to hardly anything. Im experience really painful cramps constantly, which is unusual. Im sexually active with my partner but we always use a condom. I took a test a few days ago, it came back negative. Was it too early if my period wasnt due for 2 weeks?
