I kno I'm on my AF i kno but i just can't shake this feeling that something else is going on in my lower abdomen...for the past 4 days before my AF even showed up I've been having this pulsating feeling in my lower abdomen even my DP was pressing his hand down there and was like "what's that beating?" i of course said without knowing perhaps it's a baby idk this AF feels way different than ALL my other ones and I just don't kno if I'm on my AF. how is it any way possible?
