What do y'all think

Okay so my husband and I have not been using protection, we said whatever happens, happens. So we did have sex while I was in my ovulation window. I am not supposed to start my period until the 29th, I have been pretty crampy today, like in my lower back and lower stomach, I haven't had much of an appetite either. What are some early signs of pregnancy? Or could I possibly be just trying to start early? This is what my CM looks like right now.

Please no judgement, I am just trying to get advice, without talking to anyone I know about it. Thank you ladies in advance!😘
