Hi I am currently late 3 days for my period and I have being having cramos and lower back pain for about 2-3 weeks now I took a test this morning and it came out negative what could be the problem?

You may not like this, you have either taken the test to soon; however, sounds like an S.T.D. Probably Chlamydia, see doctor quick!

I have been trying to get pregnant since April, still no luck?
