Yip, that sounds ok, check out some of the charts in our charting thread to see how it flucuates for different people.
In a perfect world it probably would stay a bit more consistent and only go up after ovulation but I think as long as you clearly have 2 phases (or kinda clearly) then it's all good. Some blips are ok. Come add your chart if you haven't already (the list is getting pretty long so sorry I can't remember) and us 'experts'

will check it out.
