What Causes Dizzy Spells And Tiredness Post Intake Of I-pill?

Hi, I had unprotected sex on Friday June 3 in the afternoon, the person ejaculated in the condom but it ended up breaking when we removed it and it all fell inside me. Then, within the hour I went and got the pill, ate and took it. The next morning I felt dizzy and tired throughout the day. Then, on Thursday 9 I had my periods ? They started heavy straight away, nothing like spotting. They lasted like a regular period, about 5-6 days. So sound June Tuesday 14 or Tuesday 15. Usually, I get really bad period pain but not this time. Then, I had some orange, re, brown discharge accompanied with a smell (however, I usually always for a few days get after my period has ended, that is is normal for me). Then, when that stopped I started lightly bleeding on Saturday 18, and it got heavier and heavier up until now. Like another period again. On the second day, I got some stomach pain but only for a few minutes. I am wondering why am I having bleeding/ having two periods in a month? How long will this last? Is it due to the morning after pill? Has it worked/ doing its job and just messing up with my periods? Will I be having 2 periods every two weeks? Should I be testing if I am pregnancy with a home test? I want to but I can t track when I have ovulated anymore etc because my cycle is a little bit messed up now. In the month of May I believe I would have missed my period or i cannot retrieve the date. But the previous months my periods were as below: Any help would be much appreciated, thanks Sophie April 11 February 28 January 1 December (2015) 3 November? October 3 September 5 August 1 July?
