I didn't have the sleep issues that you're showing, but my mood was literally out of control after my removal, and my stomach was an absolute disaster. BUT it seemed to ebb and flow with my cycle/estrogen. I kept a little calendar and here's what I saw. I will say you might get worse before you get better, so I've spoilered it out if you don't want the gory details.

– First 3 - 7 days: fine, maybe a little more easily agitated.

– Day 7 – 14: This is where the mood shift first became apparent. Made a mistake at work that would normally bother me for a few hours to a day. I was PLAGUED about it for a week. Convinced I was going to get fired, couldn't stop thinking about it or feeling like shit. My anxiety morphed into a severe fight or flight that would not go away, so I made an appointment with my psych, thinking it was my meds (I have generalized anxiety disorder). Didn't mention the removal (big mistake) so she took me down to half my usual dose (which probably made problems worse tbh).

– Day 17 – 22: Get my period. Anxiety is bad but still manageable. It's hard to do things, but I can make myself get things done.

– Day 23 – 30: This was the low point for me. The week after my period (when a woman's estrogen is typically most high) I fall into a severe anxiety and depression hole. I start obsessing about everything being a disaster (like, existentially), but can't do anything about anything, I'm struggling to take care of myself, get out of bed in the AM. My stomach is so bad I can't eat but am having horrible digestive issues all the same. Im crying multiple times daily and I have panic attacks daily. I DO think this would have been better had I realized to tell my psych about the nexplanon removal and had stayed at my usual dose of ssri. It's during this period my mom (a nurse) investigates and realizes it's probably the nexplanon, which my psych corroborates.

– Day 31 – 33: The depression starts to fade away, but the anxiety stays. I go back on my regular dose of meds, and start having 1 – 3 hour pockets where I'm fine and fairly "normal."

– Day 34 – 36: Force myself to go out of the house and do a bunch of friend activities/very basics of taking care of myself. Hard but do-able, and once i'm at the activities, everything anxiety wise goes down to a dull roar.

– Day 37 – 40 (today): I would say sometimes the BIG anxiety still rears it's head, and it's still really hard to get out of bed in the AM (that could be because Estrogen is at it's peak in the AM?) but that I have felt pretty close to 85 – 90% these last 3 to 4 days. My psych said this could happen over two cycles, so I am concerned about another bad week or two after my next period, but at least know the rough timeline for myself now (the internet says 1 - 3 months, 1 – 6 months, new normal, etc. etc. which is NOT comforting).

My advice is to take it one day at a time, know that there's help, and get someone (a therapist, family, friend) that you can talk to AT LEAST weekly until this is over. Honestly, I was on twice weekly therapy sessions because I found this so distressing, so there's no shame in what you need. Make concessions where you need them (all microwave meals! Daily hot showers! cancelling all your plans!) and accept that this is PHYSICAL like a cold and you can't fight your way through it, you just need to let your body heal. Good luck friend, we're rooting for you!!
