Had my first pregnancy this June. Misscarried at 4-5 weeks. Always get my period on the 26th. Still havent gotten my period. Took a pregnancy test this week both clear blue & first response. Very confused, i get faint lines on clear blue but negative one on the first response. Im not sure if im pregnant again or not ?? With my first pregnancy i tested at about 4 weeks and the pregnancy tests were all very much clearly positive but this time im not sure??
