I've been on the depo shot since October of 2013, I'm not quite sure when exactly I last had my period. I am sexually active with my boyfriend of almost 2 years and he doesn't wear a condom. Lately I've been having pregnancy symptoms. I took 5 tests 1 being positive and the other 4 being negative. The night I found out the test was positive I went to get blood work done to confirm that I was pregnant turns out my pregnancy hormonal level was at a 0.5.
My question is, am I pregnant and did I test too early?

With depo it is hard to say. It does such a good job, but that's also assuming that it got working right away and was administered properly. As well false positives are quite rare when it comes to HPT but they do occur. It is hard to say. Though I would trust the blood test over the urine tests.

I would wait two weeks and test again.

Absolutely any time protection is not used, there is a chance of pregnancy. Sometimes a woman can test and test, but until the pregnancy hormone kicks in (yes pregnancy hormone, you did read correctly), all tests will show negative. First morning urine is always the best to use as is more accurate then throughout the day.

And yes, blood test over anything else.

I must say though, our answers at best can only be general because we don't know your health issues if any. Best bet is your doctor. You could be a diabetic, or anything which complicates pregnancy issues.
