Ttc after miscarriage

laura

I had an early miscarriage, I waiting until I had my first period since then and since that ended I’ve been doing OPKs, the last two days I got a high result on the clear blue tests and this morning I got a negative result ..what does this mean? Why have I not got a peak? Am I not ovulating? I’ve also had intercourse on these two days and a few days before..I’ve always had regular enough cycles
