I don’t know if I’m pregnant

Okay so this is my first time writing on here I’m hoping someone has been through something similar. I miscarried at 5 weeks in May when I found out I was pregnant I didn’t even know I was a day late on my period and we had been trying so I just took it I wasn’t having any symptoms other than some mood swings and some vivid dreams I was told was a pregnancy thing I was maybe 1 or 2 waves of nausea after I found out the only one was extreme tiredness. Other than that I felt fine. Well I bled for an about a week and a couple days all my symptoms went away and I was going to the doctor regularly to make sure my HCG levels were going down and they were we started trying again on the 29th it’s been exactly 2 weeks we’ve been trying almost everyday and I’m having pregnancy symptoms my breast have been sore and tender for a week I’m having vivid dreams again, mood swings, I’m tired. I took a test yesterday (11th) negative I took a test today (12th) also negative My question is, is it to early to be feeling signs if i am pregnant? Is my body messing with me? Are my HCG levels just too low to be detected because it’s only been 2 weeks?
