Not sure when my period is due I just had a baby almost 2 months ago

I can’t tell if my eyes are playing tricks , I’ve had a few pregnancy symptoms that I usually have when pregnant. So that’s why I tested , I’ve been bleeding on and off sometimes just spotting over the last month so I’m not sure 🤦🏼‍♀️ we use protection and pull out every time . I think I just have severe line eyes ! Thanks !!
