TTC for 10 months

Erin
So hubby and I have been TTC for 10 months now. Last month was the first time I decided to take ovulation tests and I found out that I ovulate later than the apps have been telling me. Did the BD when I got the pos result (day 15 of my cycle) but still didn't conceive. Testing this month again and it's day 10 and still no pos result. Hoping to ovulate soon and conceive. I'm 30 and hubby is 38. This would be the first for both of us.  Any advice? Should I  see an ob?? Thanks in advance !
