Period 3days late and have been feeling bloated for 5 days which is not normal for me uncomfortable, negative pregnancy test day 1 of missed period?

Repeat test: You may wish to repeat the pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.
