Hi, I'm new to this so trying to get used to abbreviations and everything!
Me & my partner of 6yrs recently decided to TTC in June. However, as we were going on holiday and my last packet of pills ended the week before, I doubled up to avoid bleeding on holiday. I was prescribed antibiotics while on my last packet but, as we had already decided to try for a baby, we did not take extra precautions. After finishing the pill my "fake period" arrived as expected but it was very light (almost like heavy discharge) and only lasted a couple of days...as I had taken two packets back-to-back I was expecting a lot heavier and, in my enthusiasm, decided it must be implantation bleeding so took a test and it was negative.
I was expecting my period on17/07/13 but was aware that as this was my first period after finishing the pill that it might be late. On the 19th, I got a big lump of cervical mucus (sorry about TMI! 
) followed by some brown discharge. Since then, I've been having brown discharge each day (not much, only tiny spots here and there) and I've had two instances of pink blood. I've been feeling sick for the last three weeks (all day, not just in the morning but i cant help but think its psychological!) I did take another test last weekend, after a week of no real period, but again it showed negative.
I know that it's far too early to be worrying but I can't help it! I was on the pill for 6yrs and prior to that had regular periods on a 28 day cycle...is this normal after coming off the pill (I was on cileste) and how long should this last?
