TTC for the first. But i need to understand something before I plan. Please help.

I was suppose get my period 3 days ago. Exactly on that days i started spotting, but i do not have the flow as yet. What's happening? Shall i consider it as AF? Because even panty liner is too much for the spotting I have ( very little). But bbt is less 98.2 on day 1 97.99 day 2 and today 97.34

Please help me.

Also would like to add.

Day 1 - 22 March - Spotting

Day 2 - 23 March - Spotting

Day 3 - 24 March - Flow

Day 4 - 25 March - Flow

Day 5 - 26 March - Spotting

Which dates shall i consider as my period. Just 24 and 25 March or all from 22 - 26 March.

Was my period only for 2 days??

Please help me, i wanna plan but i need to understand this first.
