Low HCG at 30 days since Last Menstrual Period?

Brittney
So my LMP was 5/23... my cycle is 28 days EVERY SINGLE month like clockwork... test is SUPER faint...ovulation on 6/5/17...but I had an exam today & they saw Chadwick's sign with my cervix & an enlarged utuerus. Tender growing breasts, frequent urination, along with crampy feeling, bloating & gas are some things I've been dealing with for 7-10 days.  So I'm just wondering if anyone else was around 4 weeks & 2 days... & had really low HCG levels too? Should I be concerned? My body tells me I'm pregnant but the HCG isn't showing up like I would think.
