Could I be pregnant again after two miscarriage? / a little TMI

Kyra • Two angel babies;; TTC for rainbow baby #1 in Spring 2017🌸
Hey there, I'm 25 & had my first miscarriage on November 10, 2015 at almost 12 wks ... I just recently had my second miscarriage (considered a missed miscarriage) at 12  weeks and two days but technically the baby  stopped growing at 9.5 weeks .. It just took my body awhile to realize and start the miscarriage process on June 17th ... Still very heartbroken and think of my two babies everyday ..): 
So here's my question ... I got my first period about 5 weeks after the miscarriage which was from July 23-27 .. Which was normal .. And normally lasts 5/6 days as usual ... Cycle since first miscarriage has changed from 28 days to about 30-32 days in between ... I am now about 3 days late for my period and just wondering if I could already be pregnant again?! We haven't been trying as of yet and just using the pull out method... So could I of gotten preggo from the precum? 
Also just a side note - first pregnancy had ALL pregnancy symptoms ... Second pregnancy had almost none .. Only one sore nipple!! The only thing I've kind of detected that is off is that I'm quite hot all the time?
Could I be pregnant again??
