OPK Help

Avery • Mommy to my sweet rainbow Alison💜 and Rosie 💕
I believe I have had a positive on internet cheapies but I'm not 100% sure if it is or which one is. Picture in the comments. Yesterday I had heavy EWCM and what I believe to have been a positive OPK. This morning my CM is heavy and watery and I have had brief and light cramps on the left lower abdomen. The test today looks almost identical to the one from last night (12 hours before). This was also second morning urine.
