HELP! PREGNANT or NOT?!!

Nikki
Im on the pill but haven't been taking them properly the last 3 weeks! I think I might be pregnant but I haven't had my period yet (it should be coming this week)
Anyways a lil embarrassing but the last few day I have been accidentally peeing myself a lil and not feeling it until I feel warmness. Plus I've been feeling a lil off lately (emotionally and food wise) Is it a sign of pregnancy??!!
Please comment what you think !!
