HIV Rapid Test Index Value Increasing.

I was engaged in sex with different persons (HIV status unknown but risky) on the below dates Nov 6 Nov 13 Dec 07 I showed couple of symptoms like Muscle Aches, Muscle Twitching, Neck Pain, Dry glans with red sores, Sore throat etc (not all at same time) in the past 2 months (Dec 10th to Jan 31st). I'm not sure whether it's due to HIV or due to winter. However I decided to test for HIV and did the below HIV1/2 Rapid Card tests. December 11 - Non Reactive - Index 0.04 --- More than 4 weeks from 1st exposure 4 weeks from 2nd exposure 4 days from 3rd exposure January 06 - Non Reactive - Index 0.11 --- 8 weeks from 1st exposure Almost 8 weeks from 2nd exposure 30 days from 3rd exposure February 2 - Non Reactive - Index 0.23 --- More than 12 weeks from 1st exposure Almost 12 weeks from 2nd exposure 8 weeks from 3rd exposure What are my chances of testing positive and why my index value is increasing continuously from 0.04 to 0.11 to 0.23? Will it eventually cross 1.0 making it +ve ?
