need advice please

Ashley • I am where GOD has put me. 😃👫💍🤰👨‍👩‍👧🤰💞💞💞💞💞💞it's all his timing. expecting #2 Aug 2018💞💞

I have been ttc for over 1 year now. My daughter is 19 months and we want #2 to happen soon if possible. I have not been taking ovulation tests like most people do but I need advice. Is it worth the money to actually test everyday? and what tests are the best to do that with? as of right now we just BD every 2 to 3 days between my period. I have a 30-33 day cycle. So is daily opk tests worth it? and what brand and where can they be bought in bulk?
