Going by the online ovulation calculator, I was due to ovulate on the 1st of this month that night we had unprotected intercourse( I am not on the contraceptive pill)and I didn't take the plan B pill until the following evening 24 hours later, is there a chance I could be pregnant? Thanks in advance
Yes. If you were already ovulating, then Plan B cannot delay it (that's the way the Drug works).
Your calendar is just a guide, but they're usually fairly close, if your periods are regular.
If you want to avoid pregnancy, I'd advise having an IUD fitted within 5 days of the sex. This can prevent the implantation of an embryo.
