I feel like she's hinting at it and it bothers me

So lately my S.I.L has been making posts on her Facebook, they kind of seem like she's hinting that she's pregnant but isn't actually saying it. Of course she doesn't have to say it if she doesn't want to, that is 100% her choice and no one can take that away. BUT she's made posts for days in a row, one saying "of course right after I brush my teeth, then I throw up" and the comments were by her close friends saying stuff like "damn that sickness...in the morning" and "here I'll post a pic of a BABY tiger for no reason at all" then today she posted about "I've been telling y'all I can't eat meat and finally my BF got to see that it makes me sick". She's also been sharing stuff about if a guy cheats on his pregnant girlfriend then he's a little bitch and then a post about epidurals. Like am I reading too far into it or is she hinting about being pregnant. Either way, I don't really care . I'm not heartless, but she and my husband don't have a relationship anyways, she's never been nice to me, I've never even met her in person because she just couldn't be bothered to meet me when her brother and I have been together since high school. But if she turns out being pregnant. I think I will be a little upset cause she has gone on and on about hating kids and not wanting them. Meanwhile my husband and I have been trying for over a year and have had 2 chemicals and one loss at 9 weeks. I'm currently pregnant now, we haven't told anyone but my mom and aren't gonna tell anyone until our ultrasound next Wednesday. Depending on how it goes of course. Maybe I'm just being sensitive
