Symptoms of pregnancy

Steph
Hello everyone. My husband and I have been TTC for 3 months, although this is the first month of using OPKs and making sure we BD on the right days. I've had some symptoms but don't know if it's just wishful thinking! 
I had spotting (but literally just a dot or two) on 3,7 and 11DPO (today), have been feeling nauseous a little, a weird sensation in my tummy which feels a bit like butterflies but at 9DPO it was enough to take my breath away for about a minute!!! I've also had CM that is creamy with a slightly off white/yellow colour and LOTS of it. AF is due on Monday. Thank you :-) X
