i want a baby.

Okay I had the implanon BC i got it taking out! I started the pill for a month and after I finished those pills I quit takin them! How long would you say would it be before I got pregnant? Cause we have tried the past month. I've taken test after test and all of them said negative. I'm bloated really bad taste buds aren't the same and my lower back hurts bad! Is this a sign?
