As long as they have no cause for concern you should be fine. If I were you I'd find a solicitor specialising in family law, they'll be able to advise you better than anyone. A lot of it comes down to the social worker assigned to you and your case and how they perceive you as they're the ones writing any reports etc. I'd advise you to be open and honest (if it ever comes out that you've lied to them they will use this to discredit you, I tried denying my SW and it blew up in my face horribly)
Tbh it doesn't sound like you have anything to worry about but it's worth getting a solicitor just in case. Congratulations on your pregnancy and all the best x

I would be careful tbh. I personally wouldn't disclose too much information about sex work and anything your doing around it be it online, webcamming etc. If social services are aware of it and bring it up I would just say it was something I did in the past and I am no longer that person etc because unfortunately it's frowned upon especially if you have kids and have suffered mental health issues. I have kids and made that mistake too if disclosing i worked in the industry and because of that a referral was made to safeguarding(they are duty bound too) and me and my kids were classed as "vulnerable". I have had social services involved on and off for years because of a relationship I was in and to be honest the less said the better with them imo if you know you are fully capable of looking after your child physically and mentally. In regards to your mental health there is help you can access for that without the need for social services. They are probably doing a pre birth assessment to asses if you are fit enough to look after the baby when it's born which I have had done too. If you want to discuss the matter any further you can pm me. All the best x
