Help? Could I be pregnant

So I've been ttc and have been loosing weight I've been on keto for 2 months and have lost 30 pounds. This is my third period being on keto and all were right on time and mine never are I have pcos. But 2 days before I was supposed to start mine me and my husband umm... had rough sex for a long time. She was sore well after sex I wiped and It was all light pink I'm like really he made me start my period early. Well the next day i had no bleeding until the night and even then it's all like mucousy light pink stuff. And since then it's just so light and mucousy and light pink. Barley anything but I'm too afraid to risk being covered in blood to go without a tampon. Well normally I start cramping the week before my period and I always have bad cramps well I havnt had a single cramp. So it's weird and the past like 3 days I have been super nasueas trying my best not to throw up. I'm also having alot of lower back pain. Also about 2 weeks after I ovulated I started to get some pulling down in my lower abdomen/crotch area. Could I be pregnant? Or what do you think?? This is a pic of my test I took 2 days ago I thought I saw the start of somthing the pic was taken within the time frame so it's not a evap. And this is my tampon after wearing it for hours at work.. sorry Tmi
