I have been trying to get pregnant and I have taken 5 tests already and they have all came up negative. I don't understand because I'm showing most of the symptoms I have had light bleeding, nausea, tender breast, cramps, and being sleeping a lot. I am really confused why am I showing all the signs if the tests say I'm not?

Have you missed a period as that is one of the first indicators ??
Everything else could simply be PMS.

Could be your psyche. You want to get pregnant, ergo you "think" you may be.

When was your last period due?

You can not really test till you are at least 2 week pregnant. So how late are you.

Normally you will not have those signs till you are further along
