Uncertain: Rather than guessing about what these sxs mean - you can take an early pregnancy test now or if your period doesn't arrive when anticipated you can take a home pregnancy test. Take care.

Possibly: If you missed a period or are close to your period, take a home pregnancy test. They are safe, accurate and inexpensive. If test is negative, consider retaking test in 4-5 days. Best of luck!
