What do my symptoms say?

I have to say I don't find your tests very clear because after the one on the 20th you had a much lighter ovulation test and then on the 21st it was darker again. But if you're saying you had a positive ovulation test on the 20th, then you ovulated at the earliest on the 21st, meaning you're at 5 DPO today. Which is really early to have symptoms. I wouldn't say impossible, but very unlikely. It's also possible you haven't ovulated yet and that's why you're having symptoms. How long is your cycle? Is it regular? Are you still testing with ovulation tests or have you stopped? I'm keeping my fingers crossed anyway!

I'll join LM. It's definitely hard to determine when ovulation actually happened. After a positive ovulation test, it should happen within 48 hours. 5 DPO is definitely too early for pregnancy symptoms. Implantation usually occurs between 8 and 10 DPO, after which you start producing HCG. However, you can still experience symptoms due to hormonal changes. But it depends on how long you've been off the pill, your cycle regularity, etc.
