Plan B - missed period

I last day of my period was July 1st.  I had unprotected sex on July 2nd and took Plan B the same day.  I have not had a period since then.  I started spotting yesterday (August 29th) but it is just spotting.  I took home pregnancy tests last week and this week but both camp back negative.  I have been suffering from nausea and vomiting off and on for the last two weeks, but I have no other symptoms of pregnancy.  Should I just continue to wait for my period or see my doctor?

I really doubt that you are pregnant... 1. because most women don't ovulate that early and 2. the plan b method is pretty reliable! So I'd wait a few more days and if your period still doesn't come schedule an apt with your doctor!

I took the plan b pill back on Jan 20th and had a period from Jan 24 to the 31th, it's now april 28th and still no period. I've taken three home pregnancy test, a test at planned parenthood, a test at my OBGYN, and I did some blood work there too to test for pregnancy but it's all come back negative so idk.....
