Hi has anyone had experience with very faint lines on first response tests. Last cycle I had two very faint lines but then the next day my period started, I am wondering if it was a chemical. This month I am seeing the exact same line (would only be 8DPO) have tried clear blue ultra early at 9DPO and no line at all and have ran out of first response so can’t retest until I get more tomorrow. I don’t know if they are faint positives or indent lines. See picture…
