Implantation bleeding twice?!

Hey ladies, I'm needing some thoughts besides my own!

4 days ago(which was 8dpo) I had pinkish/light reddish blood when I wiped(just one wipe and was right after so and I had sex). Lastnight(11 dpo) I wiped pinkish blood (maybe 2 drops). What could this be? I did a little googleing and some pages were suggesting it could be twins! I don't think it's leftover implantation blood from four days ago bc its pink. I'm so confused! Also, I've been having dull pains in right lower abdomen for the last 4/5 days and I've had no energy the last 2 days! I'd appreciate your thoughtful comments. Have a good day girls!
