Bbt chart

Cynthia • 20, engaged and ttc.
Okay this is my bbt chart since a couple days before ovulation. Before ovulation il my temp was only 97.2 . And went up from then on and today it was only 97.9. Does this look like I could be pregnant since it isn't as low as it was before I ovulated ? I had a miscarriage March 7th. And I got a positive opk on cycle day 19. I wanna be pregnant again more than anything in the world . I think that dip in temperature could possibly be an implantation dip ? I had some minor pinching around that time, but idk. I haven't tracked this stuff before my miscarriage. I mostly just had sex all the time. Please help me out ladies, or give some useful advice ? :)
