Someone help please

I've been so not me lately. And its hurting.

So first of all I have to start off with saying that I was 5 months pregnant with twins on may and had to deliver them and I lost them.

So I am now ttc again and after that huge loss it's like a really bad need to be pregnant and hold a baby in my arms.

So as of last week I've been off I guess. Nausea every day but only throwing up a little. Bloating real bad. Cravings for salty food and chocolate. I cant sleep at night. I get less than 5 hours of sleep these past days. And then I'm so moody. Like either arguing with my husband. Or crying because I'm tired. Or really happy and motivated to get stuff done. And still no AF I also had cramps the day before yesterday.

I took a pregnancy test 2 days ago but negative (it was an internet cheapie) Idk when i ovulate and stuff since after the loss I've been irregular. But how long after the conception date would I be able to get a positive if I was ?

And if I'm not. Then this is gonna be a hell of a period 😭😭😭
