I gave birth 3 weeks ago and was told I couldn't get pregnant in the first 3 weeks post-birth and as I'm breast feeding it was unlikely after that. DH and I have had sex a couple of times this week and now I'm asking Dr. google and scaring myself that I could be pregnant again. As I say - the leaflet they have me after delivery says you can't get pregnant for the first 3 weeks not does anyone have any reassuring words?!!
