Vitamin C

Tee. 🌸 • A college student striving for greatness!
I'm to start taking 3 vitamin C's a day. (2 when I wake up, 1 before sleeping.) Just something I'm doing just in case the morning after pill didn't work. 
Background: 5/15 unprotected sex. The first round he came on my dress, without urinating we went for a round two and he claims he didn't come. I'm aware there could be sperm in his precum. 5/16 morning after pill. 5/19 two tests said negative. 5/23 light cramping and dry brown discharge. Then an 8 day early period. Lasted 3 days. Two days heavy, one day light. Two first response tests said negative. No period since then. Recent test said negative. 
Is that enough Vitamin C?
