I had un protected sex two weeks ago. It wasn’t on purpose just in the moment. I was due to have my period the 13th of December. I normally don’t miss days on my cycle there about 28 days long. I’m not on any birth control. It’s only been two days since I missed it but I’m scared! I’m only 16 and this was my first time having sex I don’t know if I should wait or take a test. Please help!!!
