Curious lang ?

Hi po! my last mens is nung Nov 20-25 pa po, i take 2 PT pero one day lang before New Year both Positive. Nagpa check npo ako sabi 6weeks going to 7weeks na.. advise for ultrasound na kaso di pa ko nakakapag ultrasound. Okay lang po ba yun? also, everyday nasakit puson ko chaka balakang pero walang bleeding.. natatakot ako baka may mangyari sakin or sa baby..
