I'd have managed fine tbh and probably really enjoyed it. I had sections (planned) both times and was back to normal levels of mobility by 4 or 5 days, and would have gone to a wedding from that point without much of a thought tbh.
And yes, I was 'bleeding' but I'm pretty used to managing social occasions on my period (and without cramps this time, hurrah!) so it was fine. I didn't leak much milk then, but did from about 3m -12m, but (a) that's what breast pads are for (b) it wasn't a big deal personally. Sand yes, I technically was 'establishing breastfeeding' but for me that was no different a week in to 3 months, or a year in. I guess I got lucky but it was kind of plug and play from birth. I know a lot of people have issues though.
Everyone is different. I'm very much an extrovert and have a lot of FOMO, and if I could stand, I could party, if you aren't that keen on parties and weddings at the best of times, your strength likely to start doing do then...
I wouldn't worry about the possible c section aspect though (emergency ones are different apparently), as recovery can be great. Again, it varies.
The truth is that you don't know how you'll feel. You may want to cuddle up at home, you may feel teary and tired. You may be bouncing on a wave of adrenaline and very eager to have fun. Or somewhere between the two. Post natal is a strange time, with heightened emotive positive and negative, and there is no 'right' way to feel.
Ps: yes, I had two very easy post natal periods. If it's a consolation, I had absolutely awful pregnancies and my children didn't sleep through for years, so you win some and lose some.
