Does this mean what i think it does???? 🙃

So this month I got PMS symptoms right on time, as usual. However my period didn't show on time. I'm now 3 days late. The last 3 days I've had a mix of milky, watery discharge and sticky stretchy discharge (it'll stretch about a half an inch before breaking). My PMS symptoms are mostly gone..

Out of sore boobs, cramps, back pain, headaches, extreme hunger, and fatigue..all I have left is mild cramps in waist line And lower back, a mild headache, I'm always thirsty, I wake up with a horrible taste In my mouth and I'm constantly craving mountain dew and Carmel. I've taken two first response tests, both are negative. But, with my first pregnancy I had negatives until 6 weeks. Could it just be too early or am I just running late? My doctor won't do blood tests until 7 days after your period would have ended. 😑
