Positive OPK on CD14 around noon and another positive CD15 around noon. Negative OPK evening of CD15. Assumed I ovulated around CD15or16. Now on CD 18 (3dpo) and yesterday night was having some cramping and fertile cm. Therefore, I took an OPK this morning and it was positive? Can you have an LH surge after ovulation or did I somehow have a false positive on CD14? Totally second guessing my body and the OPKs. This is the test from this morning. Super confused.
