Hi this may be really late but I'm new here :) I unfortunately have intense ovulation symptoms as well so you're not alone! Really bad back pain, sharp shooting pain usually on the side I ovulate, fatigue, nausea sometimes migraines, hard to sleep...ovulation takes me out!

Not sure how available this is to you but I've found sucking on tamarind candies (from India so we have lots of options) is a good remedy for the nausea, as is remembering to eat small bits of plain foods like crackers. Other than that I try and give myself the day I have intense symptoms off if I can and just lay in bed with some heat for the back/pelvic pain.
