Yes. I had light bleeding when I was pregnant. It sounds almost like your bleeding was from ovulation or just a cycly that's a little off and now you are going to start your cylcle.
The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. It involves the hormonal regulation of the ovaries and uterus and typically lasts about 28 days, although this can vary. The cycle includes menstruation, ovulation, and possible fertilization.
The thickness of the lining of the uterus decreases between day one and day five of the menstrual cycle primarily due to the shedding of the endometrial tissue during menstruation. This process is triggered by a drop in hormone levels, particularly progesterone, which leads to the breakdown and expulsion of the uterine lining. As menstruation progresses, the lining is sloughed off, resulting in a thinner endometrium by day five. After this phase, hormone levels begin to rise again, preparing the uterus for potential implantation in the following cycle.
