After miscarriage I ovulated almost right away

Now I’m so confused... did I not ovulate 😔

Since CD15 I’ve had period pains and I have had ALOT of EWCM and obvious ovulation pains but my temp is telling me different? I was so excited to see my temp go up this morning but instead I have period pains, my uterus feels sore and sensitive and my temp dipped.

I want to tell myself it’s just my thermometer as I’ve been told I need a slightly more sensitive one but it’s always worked for me and I’ve always seen ovulation...
