AF or pregnancy?

This one must be the most common question, but here I go... I’ve been TTC for one year, and this month I did SMEP, used Preseed, opk and took Pregnacare. I really thought this was going to be my month, but I’m 13DPO and since two days ago I’m feeling my usual PMS (sore breasts, cramps and gurgling noises in my tummy). I took a test this morning and BFN... I’m wondering if anybody got a positive after feeling their usual (like 100%) AF symptoms. I will keep testing if AF doesn’t show, of course. I appreciate your help ✨☺️✨
