Me and my boyfriend of 2 years have spent two days together it's all been nice he Cooked me dinner both days bought me roses so there's no reason for me to feel crappy or ill. But we had sex about an hour ago now and literally straight after I had a super bad migraine and I feel super sick , I'm currently in bed he's tucked me up bought me water and he's downstairs. Does anyone think this could be sex related or just a random sickness ?
