Pregnancy early stage lower left abdominal pain for several days, what is the reason

Patient's question:

No

Doctor's answer:

During the early stages of pregnancy when the uterus enlarges, the stretching of ligaments may cause some lower abdominal discomfort. However, it's important to rule out ectopic pregnancy. You can have an ultrasound done, or recheck progesterone and HCG after 48 hours apart.
