Light pink spotting/ please anyone help me out and help me stay positive about this cycle

Meghan

I started spotting very lightly yesterday. When I say lightly I mean LIGHTLY. AF is supposed to come on Monday. I am about 11 to 12 dpo. I am just wondering if this is implantation. Everything about this cycle has been WEIRD. I ovulated earlier bc I took clomid on days 3-7 instead of 5-9. My ovulation cramps were worse and took over one side of my body for over a week. Usually when I spot before AF its brown. My hubby and I bd last night and I noticed it was a little more of a dark pink, but again never had to put on a liner or tampon. I've been SUPER emotional and my breasts dont necessary hurt, but they feel fuller, tighter, and heavier. This usually doesn't happen to me. ANYWAY, this morning o took a cheapie Walmart cassette test and it was negative. As I would suspect bc I wouldnt even know what a positive would look like for me. Been ttc for 6 years and not even a scare and never even had a "squinter". Just tell me what you guys think is happening and if or when i should test again. I told myself if it doesn't happen this cycle I'm giving up. I'm tired of the heartache, heartbreak, and depression of getting my Hope's up for my one lifelong dream.

Again this is day 2 of this spotting.
