I'm having symptoms of pregnancy, my breast have changed, they have gotten huge (everything about them has) , they are hard, and very sore it hurts when I walk. I'm having bloating, gas, nausea, my attitude has completely changed and cramps for the past week. I took a test the 28th and it was negative. I am due for my period June 1st. I check my cervix daily and it is high and hard. I am having a hard time determining if it is open or closed. Is there a chance I am pregant? Or can it all be from end of ovulation and the start of my period?
