Hey BigCat, sorry to hear you've been having a rough time. Do not feel shit about this - You have been massively let down, it's their fault not yours. I feel so angry on your behalf
Do you realise you have now, as a PG woman, been waiting over 10 weeks for a stop smoking appt.? You could probably sue them! Do you have anybody close to you who could help you kick up a stink? If you have the energy then yes, absolutely bother the mw and make sure she chases up your therapy as well. That's probably more important and the two issues tend to go hand in hand anyway.
Meanwhile, have you thought any more about NRT?
From NHS:
Pregnancy
Most pregnant women can use NRT, but it's important to get advice from your GP or midwife first. If you can’t quit smoking on your own, they can help you assess the risks of continuing to smoke against the benefits of quitting with the help of NRT.
Using NRT is safer than smoking because it doesn't contain poisons like tar or carbon monoxide.
Your healthcare professional can advise you about NRT products such as patches, gum, lozenges, nasal sprays and inhalers. NRT products flavoured with liquorice are not recommended during pregnancy.
Patches are best avoided during pregnancy, although use of a 16-hour patch may be appropriate if you have sickness or nausea. If you do use patches, remove them before you go to bed.
You're supposed to be prescribed it and counselled about it but fuck that, they haven't delivered (tho you could try your GP?) and the risks in pregnancy are really small, especially compared to smoking.
Very good luck and try not to worry too much, huge numbers of our mothers' generation cheerfully smoked through pregnancy and the vast, vast majority of us made it through fine. just celebrate every fag you don't smoke and focus on anything about pg that you enjoy
