Pregnancy Test

My lmp was April 4 and it lasted 6 days, but I had a baby in October so my cycles are a bit irregular but I have them at least 4-6 days every month. I normally don’t have any symptoms of my cycle coming they just appear. But I started cramping the other day and thought it was my cycle and last night I was cramping too and tonight I’m cramping in my lower back. It’s not painful but they are mild cramps. I thought the cramping was a bit unusual for me so I took a hpt and it had a super faint line. And I took one tonight and it was the same... another super faint line. I’m not sure when my cycle is due again so I can’t say when for sure. Pics below. Please note I did read my test in the time frame. Just need opinions. Thanks
