PREGNANT 7 months PP???

Okay ladies I want to know if this has ever happened to any of you?

I had my baby boy 7 months ago and ever since my periods have been very irregular since January till last month they would come every two weeks and last a month. My last period was April 17th and ended May 11th, my chart says I ovulated right after my period was over so it says I ovulated 12,13 or 14, anyways it’s been more than a month since my last period started. Thursday the 24th I started to have cramps until Saturday. Sunday and Monday I had a really bad sharp pain in what seems to be around my ovary, and I’ve been reading a lot in google and I read It could be implantation cramps since it was around 10 to 12 DPO which is the time that implantation usually occurs. Idk if I could be pregnant or not due to my irregular periods but Im going crazy and i just want to wait a couple days to see if AF arrives or just to test. Has anyone gotten pregnant with irregular periods? Or has anyone had those sharp pains after cramping for a few days and end up being pregnant??
