The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.
<h3>Cell cycle checkpoints</h3>
There are 3 regulatory checkpoints in the life cycle of cells:
- G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
- G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
- M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.

During week 2 of the menstrual cycle (day 8 to day 14 or
ovulation), estrogen levels rise until it reaches its peak. Typically, days
12-14 have the highest levels of estrogen, which causes an increase in Luteinizing Hormone, which is responsible for the release of the egg cell. If
hormone levels fail to reach its peak before day 14, ovulation is not possible
because the egg cannot be released. Pregnancy may be highly unlikely.
