Depo shot and TTC.

Okay, so, my boyfriend and I have decided to have a little one of our own. We are both in fantastic places in life, financially stable, and living together. But, I have read about the depo shot side effects and how hard it is to get pregnant after getting it. I'm supposed to go in for another one in 5 days, but having pregnancy symptoms. Some people said it was depo getting cleaned out of their system. But, I'm getting a blood test result from my doctor tomorrow. I have taken pregnancy tests and had both positives and negatives. Any advice on how to get pregnant after this shot? I'm already taking prenatal vitamins (my hair and nails are growing so fast now) and eating healthier.
