Lots of discharge but no positive ovulation test.

I also used ovulation tests for the first time this month, but they were all negative every time.
I test my own discharge and cervix to know when I'm fertile, so I gave up on the ovulation tests and just "examined" myself to see when I was fertile.

If you're a bit fertile, your discharge is white and creamy, and when you're at your most fertile, it's raw white, very stretchy, and your cervix is very high and soft.

I had white, creamy discharge on Thursday, Friday, and Saturday, and on Sunday and Monday (yesterday) I had stretchy, raw white discharge, which meant I knew Sunday and Monday were my peak days.

Today I tested my discharge again, and it's back to normal—not raw white or stretchy anymore, but a bit white and creamy again, and my cervix is low and hard again, so I'm no longer fertile.

I trust this method more than ovulation tests because you have to do them at the same time every day, preferably twice a day, and you shouldn't drink for a few hours beforehand. Too much hassle for me personally. Hope this helps you! Good luck!
