My wife and I have been trying for a baby for a few months now. This month, her period lasted only half a day and it was just spots. Could this be a sign of pregnancy? We did a pregnancy test two days later, but it came out negative. Last time her period was 17 days late, but this month it was actually on time. This is the first time something like this has happened. Could there be something else going on? What's your take on this situation?

It is possible that a short and light period could be a sign of implantation bleeding, which can occur when a fertilized egg attaches to the uterine lining. However, since the pregnancy test was negative, it is less likely that this was due to pregnancy. A short and light period could be due to various reasons such as hormonal changes, stress, or changes in lifestyle. It is also possible that the menstrual cycle may vary occasionally without indicating a serious issue. If this pattern continues or if there are other concerning symptoms, it is advisable to consult a healthcare provider for further evaluation.
