Unusual chart

Natalie

Does anyone have a clue what’s happening with my chart this month? It’s usually a text book chart but this month no sustained thermal shift and two peaks? Also no peak reading on clear blue OPK but today I did a standard OPK and it was negative but a clearly visible line! Do you think I’m not going to ovulate this month? This chart is completely different to the last 6 months, please help! X
