Possibly Pregnant

My cycle was from 9/25-9/26 with 2 days of spotting. I'm not sure when I ovulated. I typically have sex on the weekend and Monday due to fiance being a truck driver. I have had so many symptoms of being pregnant. I took a test Friday and the test was very faint. Monday went for blood work and got results back yesterday and it was at 2. Has anyone experienced anything like this and was pregnant? Or HCG rised? I'm truly confused and just about ready to give up on TTC.
