Hi guys so I start my period in 4 days I've been feeling down for a few days as in temperature cold etc so I thought I had covid had a few pregnancy tests so thought let's just test thinking itl be one line. I've done 3 tests now and they all look like this. I've also been feeling very nauseous and actually vomited this morning (surly it's too early to vomit) any advise would help? X
