TTC at 38 yrs old

Yes I know my chances are slim, but I married a younger guy than me and he wants children and finally I do too. I stopped my birth control in November 2014 started just using the my days app to help figure out ovulation time from December-March, nothing happened.

So I stepped it up a notch bought the clearblue ovulation kit and have been using it for April-now. I get the smiley face, so that means something is happening.

This time around I had symptoms that point to pregnancy. Smelling weird smells, fatigue, fever once on Wednesday, tender breasts, slightly moody. Today is my 10dpo I and I tested and got a not pregnant. I am so disappointed and tired of getting no results. Hope to make an appointment with a obgyn this month to test and see if everything is working in both me and my husband.

Should I still test on my 14th day or should I just wait till a missed period, if that happens. Need some happy thoughts and advice.
