What could all this mean

Gretchen
Okay so I found out on February 6 that pregnancy wasn't viable February 8 I had the induced miscarriage which lasted about two weeks last period was March 15 my boyfriend and I had sex on March 29 and according to glow I ovulated on March 30. My next. Isn't due until April 13 while performing CM check I noticed the light brown tint to it almost like old blood it isn't heavy enough to cause discharge when I wipe after using the bathroom but was apparent during CM check could this mean that implementation is in the process of occurring and the uterus is just shutting any old blood that's there or come by period be coming 10 days early
