Help any dentists out there

Katarina
Need some major advise .... And I'm absolutely terefied it's making me ill now just thinking about it ! 
I have a serious phobia ... But it's got to the point I need to do something now. I have bad teeth I mean ... I've had bad teeth for a long time because I'm that scared to even talk about it. Like even now I'm having palpitations ... 
I need some work doing - I need ALOT of work doing ... But I'm 27weeks and don't know if there is a possibility of sedation (I don't mean like diazepam or anything I mean full on IV) 
I have a lot of problems that will probably mean surgical extractions ... That's not the issue its my front teeth that are currently my main concern ... Please please some one help . I don't know what to do :(
