PG symptoms or nah!? 😫

I started my cycle on may 20th. It lasted 5 days. My boyfriend and I DTD about 3 or 4 times during my fertile window. I know I ovulated bc cm was clad and watery and 2 days later EWCM with a dash of blood (sorry tmi I know lol). Well yesterday I got a SHARP pain on my right side that lasted a few seconds and then left. Then late last night I got a horrible headache behind my left eye that lasted until about 1 pm today. I also have been having faint cramps or “uterus twinges” almost all day accompanied by joint pains in right leg. These are the symptoms I get a few days before AF starts. I’ve NEVER had cramping in the middle of my cycle. What do you all think it could be!? Hoping for a BFP in a few days!!!
