Well thank you for your advice! You have been most helpful. (: About the STD or STI, he was my first (and only) and he was tested right before we were first "together" so I doubt that it's a STD/I. His sister had a ovarian cyst and he was worried because he said that is where her pain was when it first started bothering her. So I will take your advice and get checked out as soon as possable! Oh one more thing, since I did miss (so far one) period, do you think I should take a home pg test?
