Hey guys so I've been trying to get pregnant for over a year now but no success.. This month I didn't have my period. I'm 3 days late today. About 9 days ago I bought the 6 day first response pregnancy tests. I took two of them and they came out negative and again they were the 6 days before your period tests. I waited until the 1st of the month which was the day I was due to have my period & well nothing.. I took a pregnancy test today & came out negative. I'm also having cramps and I feel like my breasts are getting heavy. When should I try to retest again? Or what do you guys think may I possibly be pregnant or not?
