Irregular menstrual cycle 6 months postpartum

Had my second child almost 6 months ago and my menstrual cycle has been pretty out of whack since. After my first child my cycle was straight back to normal after the enitial bleed, typical 28 day cycle. But this time its very different.
15, 48 and 33 (bleed 5 days each time) and its now day 37 and still no show. Protection is being used as bub number 3 isnt on the to do list just yet, however with 1st child protection was used haha, so my trust in protection went down the toilet. But these wacky cycles are making me want to pull my hair out and ofcourse im getting every pregnancy symptom under the sun, so im hoping aunt flow shows up and we can chuck a period party. I guess what im asking is how does one deal with an insane cycle and in time could it regulate itself
