Sex 5/9 & 10 Period, very light (could have used 1 pad total) 5/20-24 headaches, weepy, sleepy 7+ days 5/31& 6/1 spotting Possible Pregnancy?

Its possible... Symptoms like this that are unusual for you can be a sign of pregnancy. However, its not certain because many other things can cause these symptoms as well. If you miss your period, you can do a home pregnancy test and find out. Best wishes!
