To take a test or not 😫

I have a 7.5 month old with a guy who we dated for 3 years then broke up when baby was 3.5 months. Since then he tried getting back together but it didn’t work out. He was a crappy bf, but we’ve been spending a lot of time together and sleeping together 😩 it’s hard raising a baby!!! ESP one that wakes up alll night to eat.... welll I missed my period 50 days ago now... I felt pregnant before I missed it, but since then I have felt fine... I am scared to death to take a test bc he is just not a person to have a baby with let alone another 😭 he just got his car repossessed and everything..... I’ve always had my life together and been successful but fell in love with the wrong guy.... I haven’t taken a test because I’m not ready to deal with these emotions 😭

I am breastfeeding so I have been hoping that maybe it is a postpartum and nursing fluke..

But I am quickly losing my milk... which I know can be because of pregnancy...

Do I take a test now and suck it up or wait a little ... 😩😩
