Early pregnancy symptoms ?

Hello, is my first time posting but I have some questions.

I am a mother of one 6 year old child, I had him with ex husband and now I’ve been divorced for 3 years and I’m trying to conceive another child with my fiancé now. He is 24 and I’m 27 and healthy. He has no kids but I do. We are trying to have our own together.

I’m asking for any advices after being so long without getting pregnant, we been trying for 3 months now and this last week I’ve been having a lot of heartburn (never happened before), frequent urinating and just a lot of bloating.

Maybe is pms I’m hoping is pregnancy.

Just asking for tips

Thanks
