very worried..

[cherylkay]

Ok I may be just stressing over nothing here but here it goes... I had a baby 17 weeks ago, as I didn't bruise or tear and had a good labour I enquired at 3 weeks about sexual intercourse the doctor gave me some contraceptive pills to take every day which I did while I decided if to have the coil or the implant I had a late period and when I did have one it was light but what's worrying me now is in the mornings I'm feeling tired sick and keep having cramps I'm very scared that I'm going to be pregnant again, is this my cycle cause I'm on the implanon or is there a possibility I may be pregnant even though I had a light bleed in december sometime?
