Help Please!!??

I dont know where to start imma try to make it as short as possible...lol i have been having Discharged or is it CM. I often get confused between them?... Im am supposed to have my monthly started last week, But that!! has been happening instead...Discharge /CM so I'm pretty worried of this is yet another false alarm and then agian I'm hopeing that this is it.That I am finally having my rainbow baby. We been trying to convienced for three years now and still counting that it will happened. I been having sore boob all day!! and that last week to i got a little bit nauseous after i have eaten. and yes sorry it look real nasty lol but I promised you that I do changed everyday today. thinking I might start soon lol thinking. a little bit more info I work in a old warehouse and some old warehouse don't have A/C so it gets pretty hots! and I will get dehydrated so I ended up drinking water and within that that two or one hour I will have to go and used the lady restroom and idk if this means something? should I test or wait another week?
