Hey ladies, 
My fiancé and I have been ttc. We had sex the day before, the day of, the day after when I was ovulating which was 8/23.  My breasts have been tender and I've had some cramping since and I got some light pink bleeding Last night which only showed while wiping. Today is started the same way but now it's heavier and brown in color. My period isnt supposed to be here for at least 8 days (although I have been irregular in the past). Do y'all think I'm pregnant or if it's just an early period? Is it implantation or not? Opinions appreciated!!
