also....in order to "now" be four weeks along AND have ultrasound pics - not those FAKE ones she sent while driving, but the real ones (ha), she would have had to make an appointment with an OB/GYN, which aren't usually done same day. go to the appointment, pay for it if she does not have insurance and then probably/maybe have a follow up appointment for an ultrasound. and ALL of that would have had to take place in a very short period of time. so she would have had to know at almost the exact moment of conception and then be RESPONSIBLE enough to do all the rest. WHICH DID NOT HAPPEN.
i do hope you start to shed some of your rather stubborn naivete, because you are gonna be a prime target for another vampire just looking for the next (willing) victim.
