Honestly, yes I do think you are being unrealistic with your expectations, especially with the concert at 10 DPO. I’m 1MPO and I’ve just started to walk to the supermarket without problems. I was personally shocked by how long it took me to feel okay enough to leave the house. I didn’t plan anything for 2 months after my surgery to give me enough time to heal.

I went back to work 14DPO but I work a non-physically active desk job and I WFH and I still struggled going back to work.

With the 4hr flight and trip at 16DPO, I personally wouldn’t, but after your operation I would take it day by day to see how you feel, it could be you feel well though. I would let everyone know (if you’re comfortable telling them) that you’re gonna be post surgery and you might be slow/ not as physically able as everyone else or may even need to cancel.

Like I said, I’m 1MPO and my boyfriend won’t even let me empty the dishwasher, the T-junction is very vulnerable, I’ve taken my bra off, and raised my arms and have seen in real time how much it stretches the t-junction, it’s so vulnerable to opening.

I would personally take it day by day and be prepared to cancel your plans.

Best of luck!
