Is this bloat normal ???

I'm 9 days post <a href="https://glowing.com/glow-fertility-program">IUI</a> (dpo)I was on clomid for the first time . I got a bfn on 8dpo. 
I'm bloated like crazy !! I feel my stomach soooo tight and stretched out like a 4-5 month pregnant lady . I'm very prone to bloating even when I'm not pmsing but not this crazy . What the hell is wrong ? Did any of you experience this while on clomid or before bfp
