TTC Baby No.2 👣💖

Me and my partner have spoken about wanted another baby. We have a beautiful 7 week old baby boy and we both love him to bits. My partner is 19 and I'm 18. We've suffered a miscarriage last April but then fell pregnant again last August and that's how we have our beautiful son. 
I'm going through really bad baby fever and I'm desperate for another! The baby will be well supported just as my son is and he or she will not be a mistake! 
When's the best time to try again as we have been trying since I was 2 weeks pp (after giving birth) but I've had my first period which ended 2 days ago and lasted 5 days .. anyone have suggestions please as I physically cannot wait any longer! 🙊💚Â
