hi, about a week ago I had sex and about 2 days after I began to feel nausea, since then we've kept tryin but I've felt very off, I'm disoriented, my face is broke out, I have a constant headache, and I feel an occasional flutter. I took a test and it was negative but after reading it I saw it may not detect it for a while longer. I'm not due for my next menstrual cycle for 2 weeks, but I'd love to know if these are symptons and if its true these test won't detect the hormone?
