I hardly felt a bit of sickness all I had was the odd nausea probably once or twice and sore boobs then one minute they were BAD next for a day or even 2-3 nothing. I would worry as I too spotted for a handful of weeks some days more than others although a scan at 7 & 8 weeks showed all was ok (HB, measured right). Everything had stopped by 12 weeks for the little symptoms I had!
Why do you not get a 12 week scan?
If you have loss of symptoms & a history it may be worth a mention to your
MW - as often this will get you a scan

You can pay for a private scan however just search 4D scan & your area they do dating scans in the same clinics.
Another thing I had was a doppler I heard baby around 10 weeks (forgot exactly without searching forum).
You shouldn't prod your belly hun - you won't feel anything enough to confirm al is ok so you'll send yourself potty & probably bean lol
