I just found out I’m pregnant, I’ve been smoking during this whole time and even just 10 mins ago I felt so sick and realised I have missed my period, I found out I’m pregnant. I’m 5 weeks

I had a miscarriage at 5 weeks and 4 days 2 months ago. I’m so scared I have put my baby in danger as I didn’t realise.

I’m so paranoid about miscarriage now as it only just recently happened. I am going to stop smoking I’ve made a appointment with the midwife next month, but can anyone help with things to replace fags just to help me stop and something less harmful to the baby.
