I took clomid days 3-10 .. I had a positive OPK on the 15th and it started dropping days after that so I ovulated on the 16th ! No sign of my period today , I am extremely tired & my nipples are extremely sore .. that sometimes happens about 3 days before my period , however they’ve been sore for about a week . I don’t have a test to take but I’ve taken one at 9-10 DPO and they were too faint to be sure .. like almost couldn’t tell without looking extremely hard . Anyone think I’m pregnant ?
