So, I’ve been testing for ovulation since 19th. I’ve been taking the supplements since then I.e folic acid. I’ve been testing daily and sometimes 2 or 3 times at different intervals of the day. These are my results up until last night. We’ve been BDing since the 19th. Have I missed it or not I’m not sure???
