Migraine after ovulation… or fertilization?🤞🏼

This is my third cycle since getting off the pill. I am 4DPO and I’ve had a migraine since yesterday. I get 3-4 per year typically and this one feels a little “too soon” since the last one, as well as lasting much longer than typical. Does anyone regularly experience migraines post-ovulation or looking back after successful implantation , did you experience a migraine? Grasping at straws hoping it’s a result of a successful implantation and not just random! 😬
