cramping

So I'm 8dpo and I've started getting the most intense cramping today and I feel bloated. I've never had cramping like this before. It feel likes some one is gouging my stomach out. I went to the ER in tears and they shrugged me off. Tylenol helps but doesn't completely take it away. I'm on clomid and this is round 3 idk if that could have anything to do with it. I've never experienced anything like this before or had cramping this bad ☹️
