So, I am 17 I missed my last period which sometimes is normal because I have irregular periods so I can go for a couple months with no period. I took a home pregnancy test because I started to get a odorless white discharge and abdominal discomfort like my period would be coming. The test came out negative and I have only had protected sex and the condom didn't break. I have read other peoples posts and it has seemed sometimes its pregnancy or yeast infection. It is possible that the test was a false negative? How long should I wait before I take it again? I took the test yesterday which is 3 weeks after my period should have arrived.
