4 months off depo shot

Holly • Expecting our last Baby to complete our family 💕💙
Hello ladies, 
Need some advice please. Was due for depo shot in beginning of August but missed as we are trying to conceive now. I've been getting my period already every month on time from when glow predicts it but it's a very light 4 day period can I still get pregnant with that? I also have been doing ovulation testing which also shows I'm ovulating? Any advice ladies
