What should I do?

So in August of 2018 my doctor prescribed clomid 50mg cd 5-7. After trying for 3 years! We got our BFP first cycle. Sadly we miscarried at 13 weeks. We waited one cycle per doctors request. Last cycle we did the exact same as the first cycle. Sadly aunt flow just showed her ugly face!! We called the doctor and he said we could change cycle days to 3-7 or he can up our dose to 100mg. I did ovulate on cd19 last cycle and we BD at least every other day. Please any advice would be amazing. Thanks in advance!!
