12.5mg a step too far?

I’m on week 6 of having gone up to 12.5mg. It’s really been kicking my ass. Ever since the first injection I’ve been feeling bloated and really uncomfortable in my stomach. It’s been a combination of stomach cramps/ache and then some pretty unpleasant number 2s. Tried more electrolytes and even some anti bloating tablets but doesn’t seem to help. Considering reducing back down to 10 or even 7.5 - would welcome other people’s input. M45 UK.
