I am 9dpo and for a few days i've been feeling a little off. Last week, I had light cramps on one side but nothing else. A few days ago, my left boob started to hurt really bad for it lasted for about an hour. The next day I felt fine but today my left nipple is feeling very sensitive than normal. I experienced runny nose, nose bleed and a lot of sneezing but it lasted for only for 2 days.
I also been feeling sleepy and i usually stay up very late in the night or morning (4 a.m or sometimes more). I now would sleep early and get at least 9 hours in and still feel tired. Usually a late afternoon cup of coffee would have me wide awake for wee hours but it doesn't work for me anymore.
Let me know if it's all in my head or if it's a possible sign of early pregnancy.
