Postpartum period.

So, I had my first postpartum period on the 8th of this month, it stopped on the 14th. Felt like the longest period I’ve ever had. Well this past Thursday morning I had such a bad cramp felt like the longest contraction of my life. The pain was so terrible I couldn’t touch my lower stomach, it lasted until the next day, we’ll Saturday I started spotting and now I’m lightly bleeding again… of course Google scared me and said ovarian CA, STD’s all this stuff. But has this happened to anyone?? I know usually postpartum periods are not regular. (2nd bby, my first I never experienced this)
