Hi,
I have a 28 day cycle and I am on the ortho evra patch I been on it for about a year and a half, usually change it every Thursday but this month I changed it to Sunday. My last period was on the 28th of the month and me and my boyfriend had intercourse a couple times between the 6th and the 11th of the next month . I been feeling nauseous for about a week now today it the 16th I also started getting mild head aches and mild dizziness and I been very tired and at night I really can't sleep is there a possibility of pregnancy?
