feeling crappy ! help 😭😂

So lately I've been feeling shitty! Waking up with sore back and neck... not being able to sleep till stupid hours in the morning... today I started to get a sharp pain in the right low side of my hip...the past few days I've had thick white discharge but tonight it's super watery and creamy white... I've had troubles getting a good breath ... and have days where I'm super hungry then not hungry at all the next day... me and my partner have had unprotected sex (pulls out..., but makes comments to say that some "came out" lol) most days since a week before ovulation up until now... why am I feeling so crappy? And Any ideas how to stop it? Also my app says I should still beovulating   xx
