Bete if your wife have still having periods after unsafe sex, then there are virtually no chances of being pregnant and these are not conclusive signs of any sort for pregnancy. Symptoms don’t come so soon anyway - and your report shows negative also. It’s perhaps fear and nervousness more than anything else, consult a registered doctor for weakness, dizziness and feeling of vomit. https://lovematters.in/hi/resource/safe-sex If you would like to join in on a further discussion on this topic, join our discussion board, "Just Ask” https://lovematters.in/en/forum
