TTC after MMC

Mandi • I`m 28 & married to the love of my life. Currently pregnant w/ my 🌈👶🏻. Angel baby 10/16/16 👼🏻 WE ARE HAVING A BOY! 1/1/18 💙
My levels have been back to zero since Saturday October 29th so there is no longer hcg in my system which can cause a false positive on OPK's. With that being said, I'm confused. The top picture was noon 15 days after mc, 2nd picture noon 16 days after mc, and 3rd is today 17 days after mc. To me, the top and bottom look the same. I generally check my cervix too but the past 4 days it has been so high it's almost out of reach, soft and open. I know the tests are not positive yet, I'm going to keep testing, just curious about opinions and if anyone else was successful with OPK's after MC
