Can anyone give me some advice

Laura

I'm now on CD 31 and still no AF and I keep getting a high result on my digital opk test with none of my usual af symptoms 🤔🤔🤔 should I take a pregnancy test??? I'm been feeling nauseous in the mornings and evenings really bad and slightly during the day for the past 3 days along with bloating, gas and horrible heartburn.......
