Hi, I have irregular periods due to pcos, I had a period nearly 4 weeks ago, and had sex nearly 3 weeks ago.. I dont normally get this feeling, but its like a 6th sense telling me im pregnant..I have a poor appetite, bu over the last few days I cant stop eating, and I feel really full now.. I get this desire to breathe in with my stomach all the time, it makes me feel better, and its like I have butterglies
