If your trying to get pregnant I would highly recommend that you purchase some OPK's (Ovulation Predictor Test) that way you can pin point the exact time when you ovulate, because if your not 100% sure of the day or days of ovulation then it's extremely hard to get pregnant since the egg only lasts for up to 24 hours. If you have intercourse before you ovulate then you can get pregnant since some sperm will servive for up to 5 days. Good luck and I hope this helps!
Unless you were ovulating very late, no you won't get pregnant. If you have regular cycles and predictable periods then you were not ovulating.
