This is my first time missing my period. It 9 days late as of Feb. 26th. My last period was January 20th. Which would make me 4 weeks pregnant if I'am. I was just wondering if there's any signs I should be looking out for. I've been having mild nausea and sharp pains in the right side of my pelvis. Almost like someone is poking it with a needle. I've been raher moody, and small things I wouldn't normally get mad about are making me so mad. Any info?
