Can anyone tell me what this is?

Sydney

This has been coming out when my honey and I do the BD. According to this app, I am 5DPO. I am crampy, unusually bloated, my nipples are super sensitive and bumpier than usual, I have a stuffy yet runny nose, I wake up with EXTREME dry mouth, my two front teeth are super sensitive and almost hurt and super gassy. I also have an appetite that's unreal. These are all new unusual symptoms than before my period each month. I'm hoping we got lucky but my CM is something I've never seem before which has me worried. TIA.
