I need opinions

So on the 3rd and 5th day of my period my bf and I had sex. We used the pullout method both times. After we had sex on the fifth day of my period I became really constipated for about a week and a half and am still having issues almost 2 weeks later. Now, I have been having tender breasts (like I do before my period starts) and am having mood swings (like pms). I am becoming very worried about being pregnant and want to hear a few opinions. Also, I ran two miles this week for the first time in about a month. Could that be why my boobs are sore?? I normally am not constipated so I'm worried about pregnancy. My period is not for another week and a half so I should not be experiencing pms this early. What do you guys think?
