Need help! Cross posting!

Alright ladies, I need help. I have absolutely no idea what is going on with my body. The first response tests were taken over the last week. Friday I went to the doctor and their test was negative, my beta HCG from that day was a 3 but then I got an 88 cent Walmart test and got a faint line tonight. The only time I’ve ever seen anything on a 88 cent test was when I was pregnant the last baby I lost on 1/25. My ovulation strips have only hit peak twice since my loss, 2/4 when I still had HCG from the baby I lost in my system ( I think it was like 183 at that point ) and then I hit another peak on 2/14. I will attach pictures of all the pregnancy tests and my ovulation tracking for y’all to see. I’m 100% calling my doctor Monday to see what they say.
