I haven t had a menstrual cycle in 4 months, my boyfriend and i are trying to conceive but the hpt comes back negative. I recently went to the ER and found out my enzymes are slightly elevated, could this be because I might be pregnant? Also, when I am on my period all I get are the cramps but now I have breast tenderness nausea, constant urination and extreme fatigue . If not pregnancy, then what could be the cause?
