Please comment! I need advise!

Ok so it has now been a week since my first IUI, I guess I'm in the "implanting stage"(if it works)  And I've been a serious emotional wreck.... I just snapped on my husband because he was joking around saying he was going to eat all the chili, like Instant RAGE. And then just started balling crying afterward.... I've been like this for 2 days now. I'm like mad, anxious, sad all at once and just feel like BURSTING. I normally get emotional when it's close to my period time but not like this.. I've never been like this before, and AF is not due till 4th. I took Famara lowest dose and a trigger shot for IUI. Is this just easy sign or pregnancy? Or is this from taking famara and trigger shot over a week ago?
