Confused!!! Kinda tmi

OK....my last AF was may 3-6 it was normal. Late but normal. We've had sex almost everyday since. Well around the 13 and 14 I had a very light orange colored cm only on my finger after checking cervix position. Iv had headache, acne, and lower back aces but figured I was getting ready to ovulate. The 14 I had egg white cm. My cervix has been high and soft. According to flow I started ovulating yest idk...today is the 18 and I have a sore throat, runny nose, headache, exhausted. My cervix is high and firm and my cm is white and sticky. What is going on??!!! My peek ovulation according to flow is may 21. I'm so confused. My AF is always off. Any advise? TTC #2
