I need some extra eyes!

So, for the last I’d say 2 months Iv had the strangest feelings in my stomach like bubbles. Iv had a baby girl 5 months ago and I can honestly say they feel slightly similar to the early days when I was pregnant with her. But Iv had my periods. But this morning Iv woke up at like 2am throwing up. Iv had a few head aches too in a couple of weeks. Which isn’t normal. I didn’t get my first period until 12 weeks after birth so Iv had a few blood tests to confirm negative for pregnancy. But with the way Iv been feeling and feelings sick it’s playing on my mind. You hear these stories of people not knowing they were pregnant.. I’m not sure what’s going on. I did a test this morning. I’m not sure there’s anything there. But here it is for a second opinion xx
