Period?

OK so...
I had my first PP period 5 weeks after LO was born. Then I got on the patch, and had another period the following month about 30 days later. I got off the patch because I'm not supposed to be taking it since I'm breastfeeding (My OB knew that too). So technically I "should" get a period at the end of this week or beginning of next. But since I'm breastfeeding, my question is, IF I don't get it, should I be worried? Or are my periods most likely going to be irregular? Before LO I was every 28 days on the dot. Should I test if I don't get it or just wait for symptoms? I don't want to waste money a test if I don't really need to because we are moving tomorrow and just paid 1050 for everything and still have to pay for gas, the trailer rental, and some house necessities. So what would you do?
