I've had the depo shot for about 5 months so far and I have decided to stop it because my body couldn't take it. I was very sick on the shot so decided to switch to the pill, I am still on the Depo for this month but my doctor instructed me to take the pill this month. I started the pill yesterday. I had unprotected sex with my boyfriend on Thursday (2-5-15), and starting from yesterday Ive had cramps sometimes it gets intense but mostly it's minor. It is sometimes all around but sometimes concentrates on my right. I've had bleeding for about four weeks before had, light but ranged from pink to red to brown but I do not get my regular period. Is there a possibility that I'm pregnant? and these cramps are implantation cramps? The Depo is still in me, plus I'm taking the pill.
