Could this be a side effect of the MAP?

[MK88]

Hi there.  My husband and I are ready to start a family.  Last week Tuesday (30.08.16) we were intimate and went all the way without any contraception.  After a bit of indecisiveness from my side as i just came off my period, we made the decision to use the MAP.  I ended up taking it on the Thursday (01.09.16), (Levonelle).  All was fine and then on Saturday morning I noticed that I was having a brownish discharge which I put down to the MAP doing its thing.  It was on and off like this mostly until Wednesday (07.09.16) this week with a few actual red bloody type discharge. Then on Thursday (08.09.16) night we went all the way with no contraception and decided that we were not going to use a MAP. I then appeared to have a very light pinky discharge which today (10.09.16) was almost like a period as such.  I have that weird feeling some get when you ovulate and when your period is on but I haven't had it like this before.  On a normal cycle, every now and then I will have a brown discharge but its a few days and then goes away again.  I don't think I could be pregnant (think its way too early to tell).  We were hoping that being intimate on Thursday may have been the first step to TTC but with the way my body is being, I doubt that we will conceive this time.  Other things I have noticed is that I seem to be peeing a lot more, haven't been feeling like myself and today I felt really tired (i was quite busy but felt tired) - not sure if my mind is overthinking things and this is a result of it.  Could this be side effects from the MAP?  Not sure what's going on.  Any help or guidance/comment would be greatly appreciated.  Thank you in advance.
