It's my first month off the iud and I'm not particularly regular, cycle varies from 3 weeks to 5 weeks. I'm using this calculator and one other, one has me 4 days dpo and one has me 5 days dpo, but it's my first month using them so idk if they're accurate at all! So anyway - I have been eating exactly the same as usual, but this evening I have had a few sudden, intense waves of nausea. They faded quickly but made me wonder. It's too soon to test right?
