Faint positive yesterday, negative today, then bleeding started?
That is called a chemical pregnancy. Fertilization happened, HCG started rising, but the embryo did not implant properly. It is an early loss, usually before 4 to 5 weeks.
In 60 to 70% cases it is because the embryo was chromosomally abnormal — nature’s way of selecting. Other reasons can be low progesterone, thyroid, or uterine factors.
One chemical pregnancy does NOT mean you are infertile. If it happens again and again, get evaluated.
Save this for the friend who needs to hear it today. This is education only, please talk to your fertility doctor for personal advice.
