can't figure out what it is

🧚🏻
Anyone help me out?
So I know this is a <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> but hey we talk about all kinds of problems on here it seems 😂😂 but lately I've not been able to eat properly.  all my life I've been dealing with chronic constipation so that's no big deal to me but I've not been able to eat! Like I can't eat two sandwiches even without being put off and almost gagging whenever I bite into more as if I've eaten too much. I'm scared I'll lose weight and I just don't know what could be wrong!! I've also vomited twice over the last two weeks but for no apparent reason. I'm just so frustrated
