I am on cd 38, mild cramps for last 8 days, no period, negative pt yesterday, positive ovulation t this morning. what is going on?

Complicated: As you know CD38 is a glycoprotein. Loss of CD38 function is associated with many bad illnesses. This does not apply to you since you are receiving it. I do not know how it would affect getting pregnant. But I think you should do another pregnancy test now and in a week. If both remain negative you have to have a sit down with your doctor
