In need of reassurance

Sorry to complain when people have struggled for years to conceive  but I'm really worrying as this is month 4 of ttc! I bd every day or at least 5 times a week but it's STILL not happening for me 💔😢 so many people tell me not to worry but i always suspect the worst! I ovulate each month as I get ovulation pain and I have a very regular cycle. I did get a bfp on the 1st month but ended up as a chemical. Sorry I'm just ranting about my worries and wanted too see if ppl think I need to be concerned...
