is the hook effect real?

Lauren
Ok so let me start off by saying I had a mmc 2 months ago so I'm super paranoid. Anyway, I got pregnant right after my mmc. At 6w3d I had an early scan. Baby was there with a good heartbeat of 121bpm. My hcg came back 61,000. I should now be 7w 4 days and of course am questioning everything. Why my boobs don't hurt as much, I feel nauseous one min then I don't. So like an idiot I took a hpt. I got a positive but test line was much fainter then previous positives I've gotten when I tested at 5ish weeks. (First pic) then I googled like a mad woman and heard about this hook effect. So I ran out to cvs bought more tests (thank god for extra bucks!) and put 50/50 water/ urine. (2nd pic) seems to me like it's legit once your hcg levels are too high?? Anyone else try this and have a successful pregnancy? Good luck to everyone!!
