no symptoms at almost 5 weeks!?

Hi all,

I am about 4 weeks and 5 days today. That isn't going from my last period as they haven't been regular. I won't be seeing a midwife for ages when I called doctor they didn't want to see me, just had to fill in a form for midwife referral and won't see one for a good few weeks yet. I have no symptoms apart from cramping and this is my 1st baby and I am terrified it means something has gone wrong or is going to go wrong!? If it wasn't for the positive tests (about 6 of them!) then I wouldn't even know I was pregnant!!! No sickness, no sore boobs, not tired. Nothing. If anyone can reassure me I would be over the moon as I know my stressing won't be doing baby any good. TIA
