How Far Along?

Found out we are expecting Jan 22. 1 day before our 2 weeks vacation out of country. Confirmed with multiple HPT and HCG bloodwork (level was 93). Have first appt with OBGYN first day when we get back. But I just wanna knowwwww!!! Different apps/sites tell me different things. Important note: my period is irregular so I dont know when I ovulated. All I know is my LMP and BD dates. HELP!!!
