Could having an std make it so you get a negative test result on a pregnancy test? My boyfriend had sex with a girl who sleeps around a lot a week before I got pregnant, and I've missed two periods since then but I keep getting negative test results on pregnancy tests.
Hi Beanaweana,
An STD should not affect the results.
Are you using your first morning urine? It does matter as it is more concentrated. In some women, for whatever reason, the tests also just DO NOT work - EVER. By default the test will show "not" pregnant.
Since you've missed two period it's time to see your doctor to find out why you aren't having your period. It may be a hormonal problem.
Good luck.
I haven't been using my first urine of the day, besides one test that I've taken, but it still came out negative. I did talk to my doctor about it and she said that the fact that I would have still had pityriasis rosea at the time I got pregnant could be affecting the pregnancy tests. I go back for blood testing on friday but I was still just wondering, thank you though!
