Had my last period on the 21st June and had a positive opk on the 6th July so had sex period never arrived on the 20th July so just assumed I was late or pregnant

Well I’ve done way too many pregnancy tests and all negative

Did another opk test on the 24th July and positive

Now have I ovulated again with a missed period can this happen I’m so confused right now

I have period and pregnancy symptoms but neither have made an appearance as of yet 🤷‍♀️🤷‍♀️
