Hi I had my blood tests done yesterday and I'm looking for some advise, my midwife said if I don't hear of them then everything is fab, but not even 24 hours later I've had a message from my doctors to contact them as soon as possible, I'm really worried unfortunately I was at work and missed the call so by time I finished the doctors had shut. What could possible be wrong any ideas? And it can't be an std I've been with my partner 5 years and only had my 1st a year ago and everything was fine xx
