How far along am I??

Christina • FTM due November 2! 🎀💕🌸
My last menstratuion was 1/26/2015, i ovulated on 2/4/2015 and we tried that day then we found out I'm pregnant on 2/16/2015 but my first appointment isn't until March 30...some apps say I'm 4weeks and some say I'm 6 weeks. I can't figure it out.
