Ladies sooooo my man & I had sex today (sorry if it's tmi) but when we were cleaning up we noticed a little bit of blood . The blood wasn't like super red . 
Now ladies I haven't had a period since April .
Is this something to be worried about ? 
Has this happened to anyone before ??
No negative comments please!!
