Ttc after chemical

So today im about 9dpo, and i had a chemical back in december, my ob told me to wait a until i got my period after the chemicql and start trying right away, so I did. Today I took a pregnancy test and I can see a vvvvfl and i’m over the moon happy, but i’m also terrified and i feel cramping a little kind of like with af but milder but im so scared to end up in another chemical. This was the first time this happened and hopefully my last time( my ob said there’s no reason to believe this will be something that will repeat) but im terrified ! Does this feeling go away ever? I started bleeding when i was doing #2 (sorry for the tmi) and now everything i feel is like im scared im going to wipe and see blood again
