Really thought this was it!

Hello,
I am feeling a little down at the moment. I had pretty much convinced myself that this was the month that I was going to conceive #2.
Was using O.P.k'S and according to that I am about 12 dpo today.
Yesterday when I woke had slight period pain and a bit of bright red blood on the toilet paper. I thought oh well not this month AF has arrived. Since then have had a bit of brown discharge (old blood?) but not much else. Very sore boobs and slight cramping.
Only noticing brown blood on the toilet paper. I thought maybe implantation?
So I got my hopes up again and did a HPT but it was negative so am now having to get used to the idea that it is back to the Fertility specialist on the 22nd and probably going down the clomid path again! :(

the day AF was due for this pregnancy i had some bleeding, i automatically assumed it was AF, none overnight so tested the following arvo and got a BFP!! theres still hope yet!

Thanks so much for the reply!
I tested again and another BFN and now AF has arrived with a vengeance!
Oh well, it just means one more month to save some more money.
So I will be off to see Dr Kate Stern on the 22nd and hopefully clomid will work its magic once again!
I really appreciate your reply and positivity, wishing you all the best for a happy, healthy pregnancy!
