Hi, I m very desperate and curious to know what this problem could be, I ve had sex 4 times with my boyfriend & last week on friday the 29th of May I had sex with my boyfriend at night & he had ejaculated a lot when we had sex 4 times even the last time we had sex he cummed inside me & we used no contraception, no protection & ever since then I keep feeling sick like I m so close to throwing up but I m not & I keep feeling tired I would sleep twice a day & even in the morning after waking up I would go back to bed again & I feel so dizzy & I ve completely lost my appetite I don t know why no matter how much I tried to eat I chuck it away I feel sick & everything tastes different& I have pains somewhere on my stomach even on the right side of my hip near my back & it s the seventh day & still feel like this , I ve started my period on monday the 1st of June 3 days after having sex, & I need help why do I feel this sick I really feel like throwing up & I have a headache?
