With DS (he's 12wks old) I remember having quite a bit of yellow mucus before the BFP. I kind of remember feeling a bit nauseas too, and headaches and lower backache.

I got my BFP at 13dpo. Very faint, but was there. I dont remember sore boobs. They did come later though. I remember not being able to walk through Wooloworths coz my nipples were tingling and hurting so much! It only ever happened when I went there! Weird huh!

The throwing up started at 5wks and continued every day without letup til I was 38wks. The nausea then stopped when DS was about a week old. My pelvis also fell apart. I had tonnes of round ligament pain from 4wks preg on and lots of bleeding during the pregnancy. It wasnt a fun 9 months at all!

But yeh, you can experience symptoms before AF due. Usually happens after implantation, which can begin to occur about 6 or so dpo. Most women implant between 10 and 12dpo though.

Luv, Amanda
