HI I was just wondering if anyone could help me? Me and my boyfriend have had unprotected intercourse and we have usually used the "pull out method" however, I am 5 days late on my period, been feeling sick on and off, weird almost twitching sensation in my abdominal area, lots of thick white discharge almost like cream, back ache, headaches and acne. I've also been feeling really thirsty and my appetite has been on and off. I've also had mild constipation. Should I be worried?
