i am 30 years old, eight months ago i had a tubal ligation.my problem is now that i have not had a period since july and i have just had a positve pregnancy test.My symptoms have been nausea,dizziness and constant tiredness but no stomach pain. I a had a pregnancy scan and a vaginal scan and they could see nothing in terms of a pregnancy and a etopic pregnancy.while having the vaginal scan i had pain and pins and needles in my left side.im booked in to see a doctor in a few days but i am very anxious and would really like some explanation as to what could be going on.Any info would be greatly appreciated.
