As my previous post have suggested, I was 14 years old when I first had unprotected sex with a boy my age which is 2 days ago, since Saturday. To be honest, my boyfriend was very rough and constantly squeezed and sucked on my nipples, which ended up hurting my breasts very much. I was incredibly anxious, with this being my first time, and therefore I was very dry. He started thrusting it in very fast for about 20 seconds, but only managed to put half of tip in before I stopped him. Luckily he did not came  or had pre ejaculation (but who knows?) 

Now, two days after the sex, my stomach have been hurting ever since the morning after, and it felt like a left side cramp, similarly to a period cramp. My breasts really hurts and are really tender and hurts quite a bit when I squeezed it. My stomach have been hurting (mild) for a while and sometime my legs shakes and they're quite weak. 

Could it possibly my PMS because we had sex the day after my ovulation and it is going to be 11 days til my next period. Is it because I am pregnant or anything? Because I am so stressed out and my stomach been hurting so badly..  

Could the pain just be because I lost my virginity or is it something different? Please tell me a way to sooth these pains and please tell me what is going wrong with me..
