Pregnant ? Positive test then faded after a while.

So I am to get my period in 5 days.

I’ve been having nausea for 2 weeks, puked once and have painful breasts, so painful I stuck ice on them. I’ve been feeling so hot and my vagina has also been hurting a bit.. I’m so nervous because last time I was pregnant I miscarried at 6 weeks. I took a pregnancy test this morning and it was faulty. No information showed. So I took another one at around 10:40 am and it showed A positive result and was there for a while and then faded.

Am I pregnant? Or will I only know when my period comes or not?
