Because of preseed, no ovulation detection

I tried using pre seed this month and my clear blue didn't detect my ovulation and LH Surge. Its always negative during the fertile window which never happened before.

I always ovulate at exactly the right time when it is on the GLOW. I wonder did anyone else face the same issue? I was suppose to ovulate on 8 or 9 June. Its 12th today.

I wasn't a big fan of using external things but after reading so many positive things about preseed, I decided to use it even when my husband didn't want me to as he is against any external thing to be entered in the body. He just want everything to be natural.

Helppp!!
