So I'm just over six weeks with first child. I have just been put on clexane injections because of past dvt (15 years ago, no predisposing factors). I have highly anxious tendencies anyway but my fear of having dvt has returned. I am convincing myself it is there. I'm reading all sorts of scenarios and to top it all off, a local lady has just died yesterday after developing a dvt which caused a heart attack after having an operation on her back! I'm so worried and scared I will form another one and have fatal consequences. I don't mind the self injections. I have had so many blood tests in past two weeks that surely something would have been picked up if something was present? What do you think? Any advice or reassurance?
