Need advice

Ciera
I had my 2nd baby a few months ago and still haven't gotten my period. On June 25th my fiance and I had sex with a condom but it came off half way due to the over load of lube we used ( it's for me). And Wednesday of last week I starting having a light period of brown and red dark discharge along with cramping, and on and off nausea. Could this of just been my period trying to start up again after having a baby or am I possibly pregnant... again!
