Yesterday I did a oralquick test, everything was followed the instructions. After 20 minutes, The Line next C is red and obvious, with a glance at it, I did not see anything wrong.But when I zoom up it, I saw a full thin line with no color, and it looks dented, like a guttered line, but it really exists. I became a little worried, so I bought another one after 2 hours, this time the colorless line did not show up, it was Negative. But I was confused what my first result stands for, and it seems that few of people has similar situation with me since I googled it a whole day. Do I need to do further test? Please give me some advice. My risk is before 3 month, had a unprotected vagina sex with a male. Thanks for your patience.
