Hi guys I am new to this site. I've been experiencing some cramps since a week ago. I've been diagnosed with pcos a few years ago. Two years ago I was prescribed clomid to help me get pregnant. After only one dose of 50mg I fell pregnant with a boy. I am planning for second one and can't wait to get pregnant again. my average cycle length is 30 days This is my cd21 could you guys think that this could be a implantation cramp? When should I take a pregnancy test?
