We are TTC and i think we might have done it this month but im so nervous and kinda scared...Not scared to be pregnant and be a mommy but scared that im gonna do something that might make me lose the baby early on and not even know it! Also my worst fear is that AF shows her ugly face! (lol). I was pretty sure i had imp bleeding on the 13th i was 9dpo then..But now that i get my hopes up more and more about YAY IM PREGNANT! all these things go through my head...what if im not really? what if AF shows? what if something happens and i dont know about it? also i have no signs or symptoms i pee a little more and my stomach hurts sometimes but thats it..Is it still to early to have any symptoms anyways? im only 11 dpo right now..can someone please just help me and put my mind at ease? (i know that wont really fully happen until i get my BFP) but i just need some input and advice from Anyone would be great! thatnks and **baby dust** to all TTC!
