Not Sure About These Symptoms

Long Post, Maybe TMI: Ok guys, this is my first time TTC since stopping my BC July 2. AF ran July 6-12. BD on the 7th, 11th, 13th, 16th, 17th, 18th, and 19th. Couple of apps have predicted my Ovulation Day being the 20th, but I checked my CM on the 20th and it was soooo not egg white, creamy and thick and definitely infertile. I also did opk tests the 17th, 18th, and 19th and the lines got weaker and weaker. I have had the following symptoms for a week now: exhaustion, breast/nipple tenderness, bloating, weak headache, and alternating constipation and diarrhea. Give it to me straight, could I have ovulated that close to the end of my period and these be symptoms?
