Desperately TTC

Is it possible to feel pregnant even before you clock a month and miss a period? Not pregnancy sign exactly but just a little instinct? Been ttc for 4 months now after a miscarriage and my cycle just came back to normal this month cause it was really messed up after the I made it possible to have sex in my fertile window which was last week and I now feel like I really did conceive..hoping for the rainbow baby to be on its way cause I'm desperately I need to be a mommy😭😭😭😭my cm is quiet egg white. .having some mild cramps and back aches my basal is high and I'm expecting my af this coming week..hope I am pregnant and can't wait to test a positive. .share your stories with me and put me in your prayers
