Hi so basically do a pregnancy test a day or two before period was due. 1st pregnancy test I did first thing in morning and both control panel and positive line was faint. Looked at test a few hours and lines had disappeared. Did two more pregnancy test different tests both came back negative on same day. I can't retest now as have started my period or T least I think bleeding was very heavy and had some small clots and stomach cramps. Nothing to bad but a bit more than normal. Is this a period or was that first test right and I'm having a early miscarriage?
