possibly, 3DPO & woke up to 35.9 degrees body temp?!

[dmestiza]

i have not been recording my BBT, and all i know from my BBT is that whilst i had my period/bleeding this cycle my body temp was around 36.1, yesterday morning my body temp was 36.2 and today went down to 35.9... silly me i should have recorded my BBT this cycle properly, but i will do it next cycle if i need 2... is 35.9 degrees body temp too low?? & is this normal?
i am possibly 3DPO, but i have been TTC for 2 weeks now- from may 11th- may 21st.
