Curious!

This is my first time posting, so I will give a little background into my ttc craziness. Lol. My fiancè and I lost our first baby back in June of this year and we have been ttc since my first normal cycle after the miscarriage. I'm currently 7 dpo which also puts me at 7 days until AF is due to make her arrival. This past week I have been experiencing headaches, tiredness and a clear stretchy discharge. I'm a googling freak and have read articles that say a clear stretchy discharge can be an early sign of pregnancy. I'm just curious if anyone has experienced this before getting their BFP or if it's just wishful thinking on mky part! Thanks!!!
