Possible chemical but no bleeding

Samantha • Double Rainbow baby born 🌈 Dec 2018

I’m unsure of exactly how far along I am because I’m breastfeeding my son and my cycle hasn’t started again but I got positive ovulation test in late September and a faint positive on a first response last week which would make be about 5 weeks. Since then my lines have faded and there now gone. I don’t think I’m having my pregnancy symptoms anymore either. I figured after some googling that I’m having a chemical pregnancy my concern is that im not bleeding at all I haven’t even spotted. I’ve had a missed miscarriage in the past so I’m kinda concerned. Any thoughts?ss
