9 months pp and worried I'm pregnant again!

Hi ladies I'm 9 months pp and I got my first period on November 30th 13 months after I got pregnant! since then my period is all over the place! my cycle is from 29 to 34 days long, I dont know when I ovulate and just to talk about my last cycle I feel like I was ovulating for 3 weeks I had eggwhite discharge also for 3 weeks and I can't figure it out any way we had unprotected sex a week after my last period finished he didn't finished inside but I know that doesn't really matter! to the point coz this is getting to long to read this is my 33rd day of this cycle and af is nowhere to be found I have light cramps that come and go and nausea but this could also be my period coming! what do I do shall I wait 3-4 days and if af is still a no show then go buy a test? i feel nothing like my first time i got pregnant back then the cramps were painfull but they didn't last long! God I'm hyperventilating I have a nine month old it feels like it's way to early for another one!!!🤦‍♀️🤦‍♀️🤦‍♀️🤷‍♀️
