I NEED SOME ADVICE PLZ!!!!

Hey ladies I need some advice plzz, ok so I haven't had my prd since feb 18 and I am like 10 days past my prd but I've been taking opk and soposaly I I ovulated on the 18 of this month and I feel like I have some symptoms like nausea, sore breast and been checking my bbt and it high above 98. So I've heard that I can make some tea of chamomile, parsley, cinnamon, rosemary, sage, and oregano to make it come but I dont want to drink that knowing that I might be pregnant, what do you suggest I do? Make the tea or wait?
