11 days missed period and negative test

Hi!

This month, i am having missed period for 11 days, last week i had a little spotting for 2 days (really only spot!) and a lot of yellowish brown discharge.

I had been taking the pregnancy test last Wednesday ( i am 7 days late that day) and it come up negative

I am afraid to take again and feel hopeless, since from i was 10 until now 27 years old, i had never been late before.

And last month i was late too for 12 days too, so it makes me late 2 months in a row.

I felt bloated, gassy, a bit cramp and keep sleepy all the time. Do anybody found out she is pregnant while having negative test and missed period for such a long time?
