TTC and TWW. Seeking support from people in the same position!

Hello, I used the forum for my last pregnancy and made some great online belly buddies. we decided it was time to TTC again as last month it seemed like I was pg (various weird symptoms, food cravings, intolerances disappeared, nausea) but AF came 2 days late (chemical pg maybe) I could have sworn I was pregnant but no BFP ( I feel like I should know how it feels as I have three children!) This month we were trying to conceive. I am day 27 (11 or 12dpo- I am not good with charting- I am making some assumptions) and I have been POAS with internet cheapies fo a couple of days. I have had faint lines but I am worried they are evap. Yes I know I shouldn't test this early!
Anyway...weird dreams, food tastes weird, nausea, tired, big boobs (could all be PMS) faint lines that could be evap. lines. I am going mad here and just wanted to touch base with some people in the same position. it is so hard to focus on anything else isn't it?
