Please help 🙏🙏need your advise

I lost my first baby girl 9 years ago, who was just 4 days old. After 3 yrs I delivered my second daughter who is 7 years now.

Both were conceived naturally.

We want a sibling for our child.

After that I had 3 consecutive failed <a href="https://glowing.com/glow-fertility-program">IUI</a>.

Then me n my husband decided to do <a href="https://glowing.com/glow-fertility-program">IVF</a>.

Bt bcoz we were new to that we don't have much info regarding this. We did just wt doctor told us to do.

I had my retrieval and then doc told me to pay more if we want to freeze all our blastocysts. Then they did the single FET. I got pregnant and all went well . At 35 week my water bag got burst and I delivered my third daughter.

Now I have two daughters bt I want to have a big family.

N this time I want to have a baby boy.

So I called my clinic and asked for PGD

Bt they told me that it is not done at their place.

I got so disheartened.

I WANT UR ADVICE REGARDING THIS.

All my three deliveries were c section .

I just delivered my third 14 days ago.

Is it safe to have 4 th section?

Wt to do to get my frozen embroys tested for PGD?

Or can I get naturally pregnant?

I am 35 years ryt now.

Should I drop the idea of having a baby boy or to have a big family?

Please guide me
