5 weeks and 2 days

Katy

First pregnancy. According to my LMP im 5 weeks and 2 days... But i swear i took the pregnancy test and only took 30 seconds for it to pop up positive. The positive line was immediate and popped up before the control line. I took it about 3rd day of missed period... Could i be farther along than i thought? My LMP was only 4 days long and im usually 7 days and sometimes 8. Idk i just have been extremely exhausted and bloating. I feel worse in the evening. Any thoughts?
