Pregnant?: On o1/01/19, the ovulation prediction kit (OPK) showed positive, but the "peak on 01/07 and 01/08" are probable errors, since the "peak" of LH production occurs within a 24 hour period. If you are not ovulating regularly, the LH may be increased longer than one day, and show positive on multiple days using the OPK. See a reproductive endocrinologist for answers, as you may not be ovulating.
