when to test?!?

been feeling under the weather, having strange vivid dreams, smell smells that are not there, mostly fish, I have had lots of cramps this month and if I wait to long to eat when I am hungry i feel really sick. to me these could be signs I am 6 days from my AF I am due for AF on the 7th of Sept. and well this is what my month was what last month looked like for me (bad pic due to no screen shot on my phone lol )

by the way my sex drive is like none suddenly and usually if he is in the mood he can get me in the mood fast right now I just am like nope...
