TMI . Cramps and Dirrahea ???

So weve been trying for almost 3 yrs. We haven't really been trying since hes been pulling out most of the time. But a few days he came in me. Instantly I get very bad cramps. Worse than period cramps. Pain relievers wont even touch it. And also dirreha.

I should be 27 DPO right now. BFN tests. What do y'all think ?
