My husband had a vasectomy 2-1/2 months ago, we had unprotected sex 3-4 weeks ago and then again 8 days ago. I am now a week past my periods due date, I have been under a lot of stress!! I have been cramping for about a week, so I have been expecting my period any day now... I have started seeing blood streaks in my discharge today and my cramping has progressivly been getting worse. I have started feeling a bit nausous this evening, maybe nurves. Is there any advise? I have scheduled an appt. but can not be seen until Thurs. but I am Very Curious!!!
