Testing from 15 days past ovulation is best to avoid a false negative from testing too early, some people have no symptoms at all, me however have got nausea, headaches, sore swollen breasts with enlarged nipples, needing to pee more often, eating more, gone off tea now drinking coffee. I tested on 15 dpo and it was neg but i'm now 18 dpo and will b testing again in the morning, hope that helps u and good luck x
You cannot really go by symptom since pregnancy symptoms and pms can be the same. You should test when your period is due or if you are late.
Yes I agree symptoms r very confusing cause they r pretty much the same as pms n it isn't til u have a positive test that u know they r pregnancy symptoms and not just the normal pms. Let us know how u get on
