When to take the pregnancy test

So recently I've been feeling kind of... pregnant. At first I thought it was just my birth control hormones (I have a skyla IUD). But so far my symptoms include

-increased hunger

-increased sleepiness (I was late to work the other day because I could not get out of bed)

-Nausea (woke up yesterday with the intense urge to vomit)

-gained 5 pounds that I can not get rid of no matter what I do

I know pregnancy tests are more accurate in the morning but I'm losing it over here lol. I do not want another baby and I'm slightly panicked about this whole thing. I had a "period" this past month but it was just light spotting more than anything and only lasted a day. Again, these things by themselves could be side effects of the IUD but all together im not so sure
