Ok so, Im still getting my head around this charting business

. Ive almost finished reading through FF's lessons which have been a huge help understanding everything. But I've got some q's that I havent found the answer to yet. Any advice from you ladies is greatly appreciated
1. Do I temp while I have AF? Does it matter either way?
2. Does Nurofen and Panadol affect your temps? Should I note them on FF?
This is my first month off the pill and Im on CD 18. Today I started spotting (sorry TMI ahead), a brown/clear mucus. Here is my
chart which may help as I am still getting familiar with it and appreciate your comments and advice.
I am not sure when/if I have ovulated and I think that FF hasnt detected it because I started temping mid-cycle.
We havent had any unprotected sex since coming off the pill, so not pg. Could the spotting be from my body adjusting from coming off the pill?
Thanks in advance ladies.
