Yes and No.
It is highly uncommon for a woman to become pregnant during her period, although it IS possible!
The first day of Menstruation is Cycle Day 1 of each cycle and lasts approximately 3-8 days. This length is unique to each person. Once menses is over, the fertile window will begin on the first day of observed cervical fluid (CF).
Sperm could stay alive in the vagina for up to 5 days, if given the alkalized environment that cervical fluid brings.
Conception can only occur during ovulation
During ovulation, a mature egg will release from an ovary, move its way through the fallopian tubes and embed itself into the nutritious uterine lining of the womb to be fertilized. This takes place within 24-48 hours.
Ovulation occurs around Cycle Day 14 (in relation to a 28 Day Cycle). If the egg does not become fertilized within the 24-48 hours, the uterine lining will shed 12-16 days later as your next period.
Some may experience spotting, or breakthrough bleeding, in between periods. This is often misled as a period, which sometimes makes it difficult to pinpoint Cycle Day 1. Track your cycles for at least 3 months to differentiate your menstrual phase versus ovulation phase.
Can a woman get pregnant during her period?
- If you experience 24 or-less day cycles, ovulation could likely occur closer to the end of menstruation. The chances of conception during menstruation are much higher in this case versus within an average 28-32 day cycle.
- Conception could take place during your period if ovulation did not occur in your previous cycle.
Track your cycles daily for at least 3 months to understand:
- Your average cycle length
- If ovulation was confirmed in your previous cycle
- Your menstrual phase versus ovulation phase
- The probability of becoming pregnant during your period
- Your basic infertile pattern (BIF)
Keep in mind
An ultrasound is the only way to predict the exact moment of ovulation, although Ovulation Predictor Kits (OPK’s) are a very common and effortless way to visually notice your fertile time. OPK’s are said to be 99% effective in predicting ovulation to conceive.
