Confused. Help.

So I traveled to see my boyfriend for a month and we had sex every day I was there. We used the pullout method because condoms bother me. Since then I had my period for 2 and a half days and it was super light bleeding. Now I have no energy, I keep getting the damn hiccups and I have acid reflux so bad it almost makes me throw up!! Also I have had the weirdest cramps in my lower abdomen ever since I left him. Also I keep getting cramps in my foot, and they go numb every once in awhile! Help please!
