So, yesterday I had two lines on the OPK and the prior days to that, infact, I usually always have 2 lines just not one darker than other until I get closer to my period. Anyways, I tested again today because yesterdays was not positive, but the line is way less darker than yesterday actually barely there. What do yall think? My period is all over the place plus sometimes I wont have a period for 2 monthd in a row and then will for 3 consecutive. Any advice would be awesome!
