Does it sound like I need to test?

I had unprotected sex on the 30th and 31 and I took a plan b on the 1st of April I only spotted (2 days) for what is supposed to be my period because it was coming up. I also just learned this a day after taking plan b that it won’t work after ovulation has happened. That was my mistake of not knowing. This is why I’m curious if I should test. I’ve been experiencing lots of symptoms but I’m not sure if it’s too early to experience all of this; mood swings, constipation, nausea, food craving, loss of appetite, hair loss, moderate amount of discharge, being very emotional, urinating more than usual. Does any of this sound like I need to test?
