During early pregnancy, one of the most pressing concerns for expectant mothers is bleeding. Many women experience varying degrees of bleeding in early pregnancy, which can cause significant anxiety and worry. Is bleeding normal? Does it indicate a threatened miscarriage? And for those undergoing US and Mexico IVF, can similar situations occur?

First, it's important to understand that early pregnancy bleeding doesn't always mean a threatened miscarriage. In many cases, it's simply a sign of implantation bleeding, which is a normal physiological phenomenon. When a fertilized egg enters and successfully implants in the uterine lining, it may cause slight bleeding. This bleeding typically appears as light pink or brown discharge, is minimal in amount, and short-lived, so there's usually no need for excessive concern.

The process of embryo implantation involves three stages: apposition, adhesion, and invasion. Typically, around the seventh day after fertilization, the fertilized egg enters the uterine cavity and begins implantation. This process takes approximately five days, though there can be significant individual variation. Some women with better physical constitutions may have a shorter implantation time, while others might need around ten days. Implantation usually occurs in the upper part of the uterine wall. At this point, Human Chorionic Gonadotropin (HCG) levels begin to increase to maintain the lifespan and function of the corpus luteum.

However, implantation bleeding can also be caused by luteal phase deficiency. Luteal phase deficiency can lead to uterine lining bleeding, which may be due to insufficient secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary gland, or an imbalance in the ratio of progesterone and estrogen synthesized by the corpus luteum itself. The amount of bleeding will vary depending on the severity of the luteal phase deficiency. If the deficiency is severe, there will be more bleeding; if it's mild, the bleeding will be relatively less.If you experience early pregnancy bleeding, there's no need to panic excessively. It's advisable to visit a professional obstetrics and gynecology hospital as early as possible for examination, particularly a blood test to check progesterone levels. 

Follow your doctor's advice and receive medication if necessary. If the bleeding is not excessive and progesterone levels are normal, usually no special treatment is needed. Simply maintain hygiene, ensure adequate rest, and avoid overexertion and late nights to provide a good environment for pregnancy preparation.Dr. Nathan Zhang of IVF USA points out that for women with a history of recurrent pregnancy loss (RPL) or missed abortions, IVF-PGT (Third-Generation IVF) can significantly reduce the risk of missed abortion caused by chromosomal issues through preimplantation genetic screening. This technology allows for detailed chromosomal screening of embryos, enabling the selection of healthy embryos for transfer. 

This process enhances the chances of successful pregnancy and lowers the risk of miscarriage. After a missed abortion, it is recommended to undergo induction or curettage, and then wait 6 to 9 months before attempting pregnancy again.
