Hello there! been lurking on this site for a while but only just posted! I appreciate that this is a long post but im looking for advice please ladies! 
I started having pregnancy symptoms about 2 weeks ago apart from sore breasts. I just "felt pregnant" Its hard to describe, I've got a 3YO DD and I felt the same very way when I fell pregnant with her but I knew from very early on as I'm quite in tune with my body.
Now this feeling of pregnancy happened before my late period, but I tested anyways and I got a BFN, I was due on my period on the 20/08 but I didn't "come on" until the 28th and it started with brown spotting which turned into a medium to light period on the 29th which only lasted the day and then it stopped and started for half a day and I had pink discharge for another day and that stopped on the 30th so I was only "on" for a day and a half if you can call it that and I'm usually bang on time each month and I always have clots but I didn't have even one this time round..so I thought this was peculiar I'm a 25 year old incase this makes any difference?
I tested again this morning but still a BFN which im certain it should be a bfp if I was but im confused as today my breasts have become slightly painful. If I was pregnant I'd be approximately 3 weeks, unless the bleeding I recently had was IB...If I am pregnant this will be a different father to my previous DD so I don't know if that could cause any changes but my thoughts are not. 
I'm really impatient and confused and its the weekend and the doctors are closed and I suffer quite badly with anxiety and the unknowing its driving me insane, has any experienced this before, what was the outcome?
Do you think it was just extreme PMS symptons and the shortest period ever or am I looking into this too much, I've read and read and im even starting to think i've convinced myself im going around the bend! I fell constantly in a daze like I've been drugged! I will keep this posted updated for anyone interested or having experienced the same thing?
thank you for reading! Please dont read and run
