Katelyn • Hello my name is Katelyn. I recently just got married to the love of my life. We have been trying on and off for about 2 months now for our first baby. We can’t wait 😊

I have had this brownish discharge for the last 3 days it also had a hint of red to it. I’m not suppose to have a period for 3 days still. What could this be? My periods usually last 7-10 days also and never come early they never have before
