I am trying to have my 2nd child. So, I am using "david" to help me. Here is the case, hope someone can give me suggestion. My 1st day M is on 1/7 and I found out 2 red lines result on both 16 and 17. So, we did on both nights. I am wondering if we need to do that again tonight?
thanks for reply! However, I didnt check my體溫 and I found the red lines didnt appear today.... does it mean I already ovulate and no need to dodo again?????
