Pregnant after Back to Back Chemicals-HELP

Hi lovely ladies. I’m 38 and I have had back to back chemical pregnancies (the last MC was Feb 10). I don’t know when I ovulated because I wasn’t tracking it. I decided to take an ovulation test today and had a leftover pregnancy test, so I figured “why not”. Has anyone had several chemicals with a successful pregnancy following right after? I’m so nervous. (Ps. I know that positive OPK’s are common during pregnancy)
