Slow rise BBT

Hello,

I have been charting for a while now and I always experience a slow rise so I can’t pin point ovulation day. Does anyone else experience this and could it prevent me from getting pregnant?

It does always go up and I know i ovulate but I have longer cycles of about 32 to 34 days.

Any advice on the topic would be much appreciated.

I have only been pregnant once but it ended up with early miscarriage.
