Weird period..

Brittany • Christian Mother , & wife ,baby number two Due march 27th??
I had very regular periods up until I had my first child . I was like clock work . However now my cycle is very wacky wich isn't concerning to me as of right now bec breast feeding is contributing to that . But last Sunday night I had light spotting it was light pink .. Thought surely it was IB then on Monday morning I woke up to "maybe " AF . I say maybe because it was a dark brown color , it lasted two days and then Today I didn't even have to wear a tampon it was so light . My last period before I got pregnant (which according to my doctor I was already pregnant )was exactly like that . I've never had a long period but I wasn't blessed with a short one either . 4-5 days maybe sometimes six . I'm wondering if I should retest ? I've been hurting in my side I would say where my ovaries are , & I've been peeing a lot .. !! I haven't be charting bbt long enough to notice a Change but my temps have been elevated I'm not sure how long though . I don't think I can use it as a reliable indication because I have to get up to a crying little one during the night some . 
​ does anyone have a similar expirence ?
