Hard to tell: At 4 weeks of pregnancy the stripe should be thickened but usually don't measure since not really prognositic of how pregnancy is going. If concerned would rather check serial blood pregnancy hormone levels. Also serial sonos would help even more. If based on your age concerned about Progesterone production can check levels or supplement if felt to be a concern. Good luck.
