Hi Sir, I had protected sex three weeks ago one day after my period ended and pretty sure nothing leaked. My husband dint penetrate in me. But now I feel nauseous and I have been having acid reflux. Iave been having diarrhea last few days and really bad cramps across my stomach. Also been getting intense bruise type on my ribs. I am really bloated with lot of gas and when I vomited my throat was burning and felt like the urge to still vomit. I am also due to start my period in 1-2 days. Am I pregnant?
