I have kept having problems with my contraceptive pill, I took two out of the last pack and kept forgetting to take them so stopped- I had a withdrawal bleed then worked out when my next period was, which is the 21st of May few days later forgot and started a new pack but only took one- I have had unprotected sex when I've not been taking them. But after I took the one pill from this pack I've had slight dots of blood when wiping but nothing heavy. Not enough to wear a pad or tampon. What's going in with me? Aha, and should I not worry until the 21st when I'm due my next period ?
