Hi Everyone, Has anyone had any luck with Tesco pregnancy tests? I could potentially be 5 weeks pregnant, had 1 period which was 7 days late, my current period is 4 days late. Extreme migraines. Occasional Nausea -- Tesco preggers tests always come back negative. Don't want to pay for a clear blue test as I've got all negatives during the past 3 months. Thoughts?
