I had intercourse may 23rd, on june 5th I had a regular period that lasted the norm of 3 days. Its july and I'm 7 weeks based off of lmp how is that?

June 5th is... the first day of your last menstrual period (LMP). Today is July 23rd. If you look at a calendar and count forward from June 5th to July 23, that's about 7 weeks. Conception usually occurs about 2 weeks after the first day of LMP, so that would be 5 weeks from date of conception. Take your pick!
