Positive OPK 3 weeks after D&C

Katie

I had a missed miscarriage found on dec 19 and D&C; the next day. Sunday I took a HPT and OPK. Both were negative. Yesterday I took another OPK and a HPT. The OPK came up positive and the HPT negative. Today’s opk is negative. Soooo is it possible to ovulate this soon???

Top opk is from Sunday

Middle is opk from last night and bottom is the negative HPT from last night as well using same pee as opk.
