I need some advice

Okay so according to my app I was suppose to ovulate on the 12th which i am just assuming I did so I waited the 2 weeks and took a test and it was negative so I kinda gave up on trying. Well my husband and I baby danced on the 17th and I had a bunch of creamy egg white cm so I assumed maybe that was my ovulation instead of the 12th so we had sex and my period was suppose to come the 26 and still had not shown up. I took a test yesterday because if I did ovulate on the 17th that would have been 2 weeks so I tested and about 5 minutes after taking the test I feel like I saw a very very very faint line my husband also seen it. I do have pictures of anyone would like to see but I don’t know if it is an actually positive or a indent line. So I took a cheap 88 cent one this morning from Walmart and read the results after 3 minutes and I didn’t see anything so I got pissed and just threw it away.. I still haven’t gotten my period and I didn’t track ovulation this month so I have no idea what is going on or what to even think. I really need some advice. This is my first time ever trying for a baby so everything is all new to me and i am learning as I go.. I will insert the pictures below.
