Very Early Pregnancy Symptom

Symptom Details

Luteal phase dip is also referred to as an "implantation dip". Defined as a drop in your basal body temperature that is equal to or greater than 0.3°F during the second half of your cycle (after ovulation). It tends to occur around the time of expected implantation (7-10 days past ovulation). It occurs more often when a women is pregnant, but can still occur during non-pregnant cycles. Even if you do not see this pattern on your BBT chart you may still be pregnant!
