Mid cycle bleeding!

Jessie
My last period was on Dec 7-12. Me and my husband started TTC this month and have been intiment several times throughout the week it said I was ovulating then on Tuesday Dec 23 I started bleeding not heavy but bring red blood. Have been bleeding for 3 days now but not as heavy Nd blood is now a brownish color. Was this my period and I just started 2 weeks early??
