I had a normal cycle on May 26th and it lasted the normal 4/5 days and I'm on a 28 day cycle. I then had a light and early cycle on June 18th. I didn't take a HPT just figured it was a little early and light. I have now found out I'm pregnant and I do not have an appt until Aug 14th because I gave them June 18th as my last cycle and now I'm wondering if I'm actually farther along and the 18th was just implantation bleeding?
