NHS pushing nicotean on me while pregnant!?

I used to smoke years ago, then I've cut down on nicotean with vaping. When I found out I was pregnant I went to 0 nicotean and I feel great! I've even stopped picking up my ecig. However I told my midwife I vaped and she arrange the NHS stop smoking service to come and see me. While arranging the appointment I had been doing well and didn't really need them, but I was guilt tripped because I was "killing my baby". So I agreed. Two women came to day and I told them I'm not a smoker, but they kept telling me I was and that I need to go on the patch that pumps nicotean through my body! They also said nothing is known about evigs and that I'm breathing in carbon monoxide, all this is a lie... So they said I need to blow in this machine and it would tell them if I've been smoking or vaping. They didn't belive I had stopped both and told me, "this is how we find out for sure people are lying to us" So I took the test and it came back clear. 😂 They told me they'd call in a few week to make sure I wasn't still smoking! I told them I wasnt going to risk getting addicted to nicotean again just so they can "help" me so I become one of their statistics. They've not helped me, they're not bothered I'm incubating a baby, they get money for every person they "help". If you vape and are trying your best to stop then carry on doing that! Dont let anyone get you hooked again.
