Faint Line question

okay so this is a first for me. we have always gotten pregnant through stimulated cycle with progesterone suppositories so my test have alway been very positive with no question (I dont know if that really has anything to do with it or not) however my test yesterday and today 1 day prior to PERIOD and day period was supposed to start they are really faint. im just wondering is this normal or maybe this is not viable. I got blood drawn yesterday at the ofdive just waiting for results is killing me. we lost our sweet boy on May 14th at 18weeks gestation. so just really nervous as well. TIA
