TTC after a Tubal reversal

Shay
Has anyone had a tubal reversal and if so how long sit it take before you conceived? I recently had a tubal reversal on April 20th 2017 and we already have two girls and so we are wanting to try for a boy...my doctor that done the tubal said their was no time to wait to start at it again, but I wasn't really sore after my surgery so we tried and today makes my second day late on my period but I took a HPT it said negative but I'm really starting to wonder.
