Hi,
I would definatly suggest going back for a blood test, It is possible to receive a negative result at the doctors as they dont tend to be as sensative as a home pregnancy test.
It also doesnt at all mean your having an ectopic pregnancy.
When i had an ectopic preg tests at the hosp & home both came up nagative the only symtoms i had was a horrible pain in my sholder and i bled like a brown blood for about 4weeks i could also feel a lump just above my bikini line unfortunatly by the time it was realised i was prego it had already ruptured, so i think if the docs thought you were having symptoms of an ectopic pregnancy they would monitor you closely as it can kill you. The symptoms of ectopic tend to be the same- bleeding,hurts when you do bowl movements,pain in tummy eather side, high temp and pain in the tip of your right sholder.
It doesnt say where your from but if your in the UK you can pop to a walk in centre or A&E and express your concerns so they can do you a HCG blood test.
I wish you the best of luck.
What do you mean it came up possible? Do you mean your blood test was inconclusive? If it was an ectopic, you would have pain in either the right or left side of your abdomen and you would generally test positive.
