pregnant or not?

[ramosjess72]

On the 1st of april i had an iud removed, which i have had for the past 2 1/2 years. Since then i have had unprotectd intercourse with my husband in hopes to become pregnant. I never recieved my menses which is unusual for me since the past 6 years that i can remember never missed one. I keep close track of my cycle to the approximent day that it will begin. I have taken many pregnancy test but all revail negitive. i started spotting about 4 days ago but was really breifonly lasted one day. Could that be the egg implanting? Could i still be pregnant? Or did i possibly miss my period do to the removal of the iud?
