Help!!

I'm almost two weeks late and I never go over 35 days in my cycle. I did have possible implantation bleeding about 5 DPO it was more red than pink. I have a pic I can post. But I didn't think much of it. I've been having a lot of pregnancy symptoms. Sore breasts, lightheaded, headaches, cramping, very moody etc. I have take 3 negative pregnancy tests but one today had a very very faint line. Also a blood test that was negative but they ordered another one for me to take in a few days or so that is more detailed. This would be my first so I have no idea!! Any advice?!
