Birth Control

I started to take the combined pill last week that I had taken before TTC. After being off the pill for 2 years I didn’t really like the thought of having to put more hormones in my body as I felt happier being off it. I do want another baby but want to wait until my baby is 1/2 years. After taking it I feel more moody and my sex drive has gone and I also feel more frumpy. I’m thinking about coming off it and just using condoms for now as even if we did get pregnant it wouldn’t be the end of the world as we do want another baby eventually! Has anyone used condoms as an effective method?
