Negative home preg test be accurate 32 days after sex? 6 weeks since lmp. somewhat irregular periods. tested last week neg. do i need to repeat test

Should be accurate: 32 days after your last intercourse a pregnancy test should be positive if you are pregnant but repeating the test can't hurt anything. It would be a good idea to be seen and look into what is causing such irregular periods ( thyroid disease, adrenal disease, PCOS, pituitary tumor, medications, stress, exercise, etc.) best wishes. Hope this helps.
