Could you be pregnant if your period came on the day it was due and only lasted two days instead of your usual five days you have also been suffering from a lot of heartburn which you never had before?

Yes, it is possible to be pregnant even if your period comes on time and is shorter than usual, as some women experience lighter bleeding during early pregnancy, often referred to as implantation bleeding. Heartburn can also be a symptom of pregnancy due to hormonal changes and increased pressure on the stomach. If you're concerned about a potential pregnancy, it's best to take a home pregnancy test or consult a healthcare professional for further guidance.
