I am 25 and have just found out that I am 5 weeks pregnant (first timer). I am extremely worried as for the past two nights I have had very painful cramp in my lower stomach and then during the day dull aching period pains, I woke up three times last night with the pain as it was so bad and felt like I had to breath myself through it. I have booked an appointment with my doctor for today but just wondered whether any one else has experienced this. Feels like I have gone from shock on finding out to just worry, can't wait to get to 12 weeks when the worrying can ease!
