miscarriage then ttc

Cassie
Hi everyone, I don't normally post on the community. But I am very confused and just wondering if anyone else has experienced what I am experiencing. I had a miscarriage on the 27th of October completely moss carried on the 28th. I normally have a cycle of 28 days. Me and my partner then gave it a couple of months before starting to try it again. I had my af on the 19th of November and then the 24th of December. This week I should be ovulating according to the glow calendar but tonight I have gone to the toilet when wiped there was red blood could it be my Af as this isn't due till end of next week at least. 
Hope to hear from some people with advice as am finding this stressful as was excited about ttc this week but now bleeding  xxx
