Can my cycles be normal? Could the fact that I stopped breastfeeding only 4 months ago play a role?

Yes, it is possible for your cycles to be normal even after stopping breastfeeding. It is normal to experience some irregularities in your periods for up to 3 months after stopping breastfeeding. Using an ovulation tracking app like Flo can help you better predict your ovulation period. With a cycle length of 27 days, ovulation typically occurs around the 12th to 13th day of your cycle. It is recommended to have intercourse every 2 days starting from day 10 of your cycle to maximize your chances of conception. Keep track of physical symptoms during ovulation and consider starting intercourse a bit earlier than usual to increase your chances of conception, as sperm can survive up to 5 days and eggs up to 48 hours.
