Worried

Today is day 4 of flashing OPK. Second cycle after MC. Last cycle I had no flashing and went right to solid smiley on day 14 but my chart looked more like day 18.

I’m feeling twinges and had some EWCM that made me think I’m ovulating. I’m hoping to see a spike in temp tomorrow but I never have had trouble getting pregnant. Just staying pregnant. Now I feel like it’s never going to work..any advice based on my chart??
