hey hun, i just wanted to share what happend with me (hopefully to make you feel better!) :)
I was getting very very bad pains (not just the period pains you hear about), no bleeding
I went to my doc, (i didnt know i was preg at this point), he said go home, and do a test, if its pos, go straight to a&e in case it is ectopic
So off i went, at the time i was about 5 weeks, i had blood tests ever 2 days to check everything was developing ok, then at week 6 i had a scan (too early to see), so i went back the next week and saw that the pregnancy was devloping in the correct place, then i had another scan about a week and a half later, and we saw the heartbeat :o
The scan also showed the pain i had was due to a cyst that grows over the devolping egg to protect it (it was breaking away as it had done its job, and that is what the pain was), apparently it is very common.
I have just had my 20 week scan and my little boy is perfect :)
