11 days late. Anyone get mixed hpt results then a positive blood test?

AF is 11 days late. I have had 3 faint positives (Target brand pink dye) and 4 negatives (Clear Blue digital and dollar tree). 

April was my first month off birth control in almost 8 years. I have been on Metformin for 9 years from PCOS. However, my last gyno appointment they said they do not see me as a pcos woman any longer. I have read so much controversy online about that. Many say once you have PCOS, you can't get rid of it. So I have no idea. 

About 2 weeks ago I had two straight days of extreme nausea and that is what encouraged me to buy pregnancy tests (started with Target brand).

I have had off and on symptoms of nausea (which I am not someone who gets nauseous ever, I can count on one hand the amount of times in my life that I have gotten sick), sore nipples, fatigue, forgetfullness, moody (like extreme according to hubby), gas (tmi but being gassy is very abnormal for me), crazy cravings for jalapenos (which I have never liked), pimples (bye bye nice complexion), unusual cramps, peeing more than usual (I am a teacher and have trained my bladder for only going maybe 3 times while at work and I have had several days now where I have to grab someone to watch my class so I can run to the bathroom) and heartburn (which could just be from the jalapenos I keep eating!)

Is it possible to have negative hpt and then a positive blood test? What about if the blood test today comes back negative? Is there a chance that my levels are just to low? What should be my next steps from there? If pregnant, I would be in my 5th week.

Hubby and I aren't excatly ttc but we aren't preventing either. We have just decided that we are ready but won't exhaust ourselves trying, so whatever happens, happens. Therefore, I don't think I have been playing mind games with myself, I feel like these symptoms are all very real. My hubby feels the same, especially about my jalapeno cravings and extreme mood swings. However, the mixed results of hpt are confusing us a lot!

Any advice and thoughts are appreciated? Thanks!!! Included are two of my positives (faint) from about 2 weeks ago.
