Okay so I am late by four days. Haven’t been in years other then when I had my daughter. I started taking a multivitamin right after my last period. My husband and I have been mostly using the withdrawal method with an occasional condom here and there. We typically don’t have sex during my most fertile time either. I logged that we had sex the first day of fertile week with withdrawal used. I’ve had mild cramps on and off. I took two test one in the evening one in the morning on day three of missed period they were negative. Still no bleeding. Could my multivitamin thrown me out of whack? Did I just test to early and could be pregnant?
