ttc/af confusion?!

so af was due 10/18 but I woke up to the witch yesterday morning! 👿... or so I think 🤔 the reason I'm confused is because... 1: I had a horribly sharp stab pain in "my area" yesterday that I've never felt before. 2: I drink a cup of coffee pretty much everyday and ofcourse it makes you pee more but the past few days I've drank coffee I have to rush to the bathroom to pee atleast 6 times in about hour in half or so. 3: (probably not that great for me) but for as long as I can remember I have only ate one big meal a day or 2-3 small snack meals a day and lately I'll eat decent filling meal then feel like starvy naseous if that makes sense? 4: before ttc I NEVER experienced any pre af symptoms cept maybe a few small cramps day before and now my boob's have been hurting/sensitive for about a week now. 5: my af is normally medium to heavy flow for 3-4 days but this is a light af. 6:this may not mean anything... I have NEVER cracked an egg w more than one yolk inside n last night I did. maybe another person I know is pregnant? but here's to hoping these are all good signs for me. I'm just so confused cuz I really think this is af for me n I'm out this month but my body seems to be reacting to this af differently
