Undecided about Tubal

So, due to the doc accidentally removing my epidural line, I didn't get my tubal done this time around. Funny thing, same thing happened 5yrs ago, in another hospital. Anyway, we now have 5 children and my husband and I have talked about having another in 5-6yrs, just like we did with our last. However, we've already scheduled for the ligation in a few weeks. At one point, I'm ready to be done with having kids and I just wanna enjoy my babies who are already here. On the other hand, we both kinda wanna go again, hopefully we'd get another girl to even us out again lol. We're a pretty successful family, financially stable, well rounded, own our home and healthy. However, I do know anything can happen and things change but I don't wanna think half empty and be pessimistic, so I wanna live our lives happily and enjoy our blessings. Should we just use a birth control method and try for another baby in 5-6yrs or is it time to hang it up??
