I check it right before pitching at 70 degrees. I used a buddies hydrometer and refractometer and same results. 7lbs LME for five gallons

I started brewing a month or so and I'm on my third batch. All three batches I've taste great but my OG has been really low. 1.012 for an IPA. I've followed the directions to a t and scrape as much extract as I can. What is happening and how do I get my OG up to the 1.05's where it should be?
