Question and panicked!

Julie • Age 38 one round of chlomid and loss twins at ten weeks.. second round of clomid and now expecting a baby boy.

Ok ladies ! I currently just turned 39 and last summer I conceived twins and lost them on clomid. I am now 11 weeks pregnant with a healthy baby boy after two rounds of clomid. I’m jumping the gun here I know .. I want to try for another baby after this little guy is here. I’ve heard doctors advise you to wait 18 months ! I’m kind of worried about that because of my age!!! Thoughts from anyone ?!!!
