text: pregnancy tests? how common is it to take 5 over the counter pregnancy tests and they all turn out negative? i had a really light period---im on the pill and it was brown discharge for only a couple hours. i took the test before my period, after the light period, and then 19 days after i had sex with my  boyfriend. do you want to be pregnant? well if the pregnancy test kit shows negative, then you are probably not pregnant. what's more, you are on pill. but if you want a definite answer, approach a doctor.
