TTC after MC. I need BBT help!

Nina
Hello everyone. Could someone please help me here? Anyone with experienced charting? This is my first complete month of charting after my first pregnancy ended in a miscarriage in December. I feel like my chart looks like mountains. After my temp spike last cycle I notice that my temperature dropped below the cover line twice. Then I got my period (first period after MC in December).
I should be ovulating soon, but I feel as though my temperatures should all be consistently low right? but sometimes it looks like there's a spike and then it drops. Still no sign of EWCM, but I feel like it should be coming soon because I'm getting cramps, so maybe ovulation is close. 
Does my chart look normal to you girls?
