Low sex drive - pregnancy symptom?

Hey ladies. I'm 9 DPO and normally have an extreme high sex drive. This week however although we have had sex I'm not exactly raring to go if you know what I mean. It may mean nothing but could this be an early pregnancy symptom. I'm desperately trying not to test early and I've managed it so far - glow even told me not to today! Definitely feel different this cycle though. Thanks in advance and baby dus to you all! Xx
