First month off IUD

Good god I was warned that merina crash and hormone imbalance could be a thing ( I’m 31 and been on crezette from 15 - 23 and merina 23-31 ) I have had every single early pregnancy symptom in the past two weeks ( testing negative) and completely driven myself insane, today I woke up to very light bleeding which would be day 20 of my cycle (I know they can be irregular in the first few months) but I still am going loopy thinking I got pregnant. Does this get easier ? I felt so fucking terrible and extremely emotional ( my partner has been an absolute ray of sunshine while I have been an emotional and physical wreck of a person) Any tips for starting to try, especially for the emotional side of it ? I use Flo to track and have been tracking for months in general to get used to it, my diet is very good, I had all my pre conception bloods done at the doctors and had fertility tests done a few months back ( I’ve a lower AMH for my age but not extremely low )

How do I remain a person in all of this ? Does it get easier or feel more normal ?
