so me and my fiance had sex about 3 days before ovulation. its now been 6days. since then i have been getting mild cramps on and off, headaches, sensitive nipples, slight nausea and bloating and urinating more. i havent had any implantation bleeding yet either. this would be my 3rd pregnancy. i currently have a 5yr old and a few month ago i had a chemical pregnancy.
