Confused with PMS symptoms.

I have bad cramps today but took a test cause I had unprotected intercourse the week of ovulation.ive got PCOS so I don't always ovulate. The first two are around ovulation. The next two are from this morning. The fifth is a control with water. I heard these mom med tests have bad batches right now. In fact The lines I did see were faint but got a bit darker outside the time The next two are from this afternoon. And the last one is from the dollar store.which at 5 mins it was very clearly negative but a line started to appear a few mins later. The purple one is from Walmart and was also negative and has a very light shadow but read these have indent lines. The last two photos are right after the timer went off for the Walmart test and dollar tree test.
