Please help with advise on symptoms.

Emma • Baby #1 - Boy 💙 born 14 July 2015!!
I have tested positive since Thursday. the picture is my most recent test who h was Monday. I'm now at 14dpo and have had a cold and sore throat since the weekend and a banging headache for the past 3 days which I rarely ever get? Are these early signs of pregnancy as other than that I don't have any symptoms? Your advise is appreciated pleeeeaaasssseeee.
