Discharge? TMI picture

Anybody know what kind of discharge this is? I’m a breastfeeding mum (9m) and only had 3 light periods. Been having this for about a week now, I feel it trickling out of me sometimes which makes me feel like it’s my period so panic. I have had unprotected sex but like I say I haven’t had a period so wouldn’t know whether I’m late or not/pregnant. When I was I first pregnant I had no symptoms other than a late period by 12 days...sorry for Tmi
