Is this weird or am I just taking it personal ?

Is this weird or am I just taking this personally when I shouldn’t ? Both my friends and me all have kids. I have 2, my other friend has 2, and my other friend has 1. Usually at least once a week we’ll all get together and do something fun with the kids or all get together and go to one of ours house and let the kids play together but lately they don’t invite me or my kids to anything anymore and I think it’s because I’m pregnant again or something because that’s when I noticed I stopped being invited to stuff. This is what I think is weird though, like I don’t care if they just wanna do stuff together and not invite me whatever, but they’re going out of their way to lie about stuff before I even know about it. For example I text both of them a few days ago and neither one of them responded all day which no big deal. But then that night they both text me and was like “sorry we went to bed early we were just so tired” that’s totally fine but then come to find out they posted pics on social media of them and their kids that evening all out to eat at a restaurant together which is something they usually invite me and mine to but they didn’t. Then 2 days after that both of them again didn’t talk to me all day then same excuse said they went to bed early and were just hanging out at home all day and tired but come to find out they actually all went swimming all day and again didn’t invite me. This has happened multiple times over the past month but they’ve just recently started lying about it or trying to like hide it idk? Like is that weird ? Maybe I’m just being dramatic because my pregnancy hormones or whatever but it kinda hurts my feelings. We used to do stuff together all the time and now I feel like they avoid me doing stuff with them idk. They are my only friends with kids so it was nice having other moms to do stuff with but I feel like they don’t wanna hang out with me anymore
