I'm currently 5 months postpartum and still breastfeeding my son. I haven't had a period yet and am on the mini pill but I take random pregnancy tests every few weeks just to make sure. I took one a week ago and it had a faint line. Took 3 more throughout the week with no lines then one last night had another faint line. Took a digital one this morning and it said not pregnant. So I don't think I'm pregnant but what are the chances of having 2/6 test being faulty?!? So confused!! Picture of the two faint lines a week apart
