Ttc. I have taken two tests and both came back negative. Spotted mainly for 2-3 days. I suspect I am but tests say no. What should I do?

Ttc. I have taken two tests and both came back negative. Spotted mainly for 2-3 days. I suspect I am but tests say no. What should I do?

Trust the test: Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection. Sounds like just a late period. ...Read more

The other possibility that I've commonly found is low thyroid function. Sometimes birth control pills can inhibit menstruation. Regards, dr. Tedde rinker. ...Read more
