So yesterday I was so excited i decided just to take a clearblue test in the mid afternoon and first the line came out out faint then with a few more mins later came out alil more darker but now this morning i took another test and just one line came out on both clearblue and first response test.. period will start within the next 4 days should i keep testing like 2x a day or just wait until i miss my period?
