Reoccurring stomach ache and feeling sick. Period/anxiety/health problem?

Hi guys,

I’m 17 years old and I’ve had problems with my stomach when I was younger because I had a twisted gut. I had it all sorted years ago and I’d been fine for years. When I was around 11 I kept getting weird stomach aches all the time but they weren’t painful, they were more just uncomfortable like I constantly have a tight belt on but we didn’t do anything about it and it just kind of went away.

I get this kind of stomach ache and feel sick when I get anxious (I have anxiety) but now I’m getting it every day even when I don’t feel anxious. I don’t know if it’s subconscious anxiety or something because I just started a levels and I get this feeling a lot during school and I get really stressed that I will be sick and school and I miss a lot of school because of it. The other day I was at my boyfriend’s house and I felt so sick out of nowhere when we were just chilling out. This was when my period was finishing and I always presumed this problem was because of my period but I experience it when I’m not on it now and I feel like its disrulpting my daily life as I’m constantly worrying about it. I asked my mum if we could go to the doctor but she says they probably won’t do anything and seems reluctant to go.

Do you think I might have a health problem or do you think its all my head making me think I’m ill when I’m anxious?
