So my LMP was 4/17 I started BC on that day. I stopped taking my BC about 7 week ago because I couldn't remember , and I wasn't taking it at the same time! I have had unprotected sex, the week that I was NOT on BC. It's not possible for me to be preggo right? Because I haven't bled? Took OPK n HPT both neg. I was going to wait a month too see if I bleed... has anyone experienced this?
