HELP! 4 C SECTIONS LATER....

So, I have 3 children via C- Section (4th was a bladder repair situation being that they nicked my bladder during my 3rd baby and closed me back up, early septic and 10+ pounds of urine drained later....I am alive GLORY TO GOD!!!)

But my baby girl is 9 months old and my DH and I get busy when we get the chance (2 teens and still healing overall), I noticed that my period was strange this month....I used the bathroom to tinkle (if you will) and upon wiping, I noticed light bleeding...today is day 9...my periods stop at day 4. I'm confused. Its been dark and had really bad headaches....aside from that, nothing.

***when I found out I was pregnant with my girl, I seriously had a period the first 2 months. As well as my boys. my body is weird with pregnancy. Could I be...? Has anyone experienced anything similar?

thank you in advance! blessings to you all!
