A blissful blurr of perfect part deux???

I realize this is long but please read and hopefully help.

Last month my period was 3 days late. It started Oct. 30th (My normal cycle is like clockwork every 24 days). The period started on a Sunday night (10pm) and was very light. Monday was medium, Tuesday was light and by Wednesday it stopped.
I'm not someone who likes to wait so Friday I tested. The result was Negative.
My breast swelling that I normally have only right before my cycle hasn't gone away - they've been very very tender and swollen for weeks now. Normally by day 3 of my cycle they start to "deflate".

Last week up I noticed a white-ish discharge - something I've never seen before.

Today I used the restroom and about an hour later felt a "ping" in my groin area - went back to the bathroom and got what I think is my period. My period isn't supossed to be here until next week - in 7 days exactly. I have never been this early. At the most it's been 1 day early.
I've read where implantation bleeding may occur but this blood is light red if not pink and implantation is supposed to be dark or brown...
My husband and I have been trying for 2 years. We were 8 weeks pregnant when I suffered an ectopic pregnancy (MC'd on Labor Day of all days...) that just devistated us. I don't want to get my hopes up and test test test...
I've also had a few mood swings, crying...and a headache about daily (nothing major just a slight). Honestly I couldn't tell you if any of these signs happened before with our last pregnancy - Once we found out we were pregant life became a blissful blurr of perfect.

Does anyone have any similar stories or advice that they can share with me? I need alittle support.
