Any insight please!

Ok so saturday I took a test at 7:30am, it was positive. I got to work and noticed some spotting that lasted all day. around 7 pm, I took another test, and it was positive, and I was still spotting. Sunday, around 6:30am, I woke up, no spotting and took a test, it was negative. I took another at 9am and it was positive but the line was so faint is was almost invisible. No spotting the rest of the day. I took another at 7:30 PM and it was positive. So today, I woke around 8 and took a test and it was negative. I took one more around 1 and it was, again, an almost invisible positive. I'm supposed to get my period tomorrow but haven't had any bad cramps or anything. please help!

PS: The spotting was very light pink, accompanied with tiny cramps that didn't last long.
