help (20F) & (24M)

I came off nexplanon early last month, we had unprotected sex towards the end of the month and I took plan b on may 4th.

We sat down and decided we do want to start a family, since then we’ve been TTC, I have most of the pregnancy symptoms but when is best to test?

My period is irregular due to being on birth control for 7 years straight 😖
