CD 17

So I had my period on October 20th and had unprotected sex on October 30th I also had my iud removed on October 18th! Today is CD 17 and I was spotting for about 5 days and stopped yesterday it wasn’t like a period it had fertile cm mixed in! Well today I’ve noticed I’m feeling irritable and I feel hungry but when I eat I just can’t so (loss of appetite) ?? Has anyone experienced this before
