Early pregnancy questions!

This is my rainbow baby! First pregnancy was discovered October 4th 2018. Only last a little. Miscarried on October 15th 2018.

The first test was taken March 8th 2019 the one every day until today March 12th lines are definitely getting darker!!

I can’t tell how pregnant I am because my periods are irregular and i didn’t test ovulation this month. But my calendar is accurate for when I had sex and last period. What do you guys think?

Also, I am having different symptoms first pregnancy I had was continuous painful cramping.

Now I have headache, increased hunger & peeing. I feel like it’s in my head because I’m probably only 2 or 3 weeks pregnant.

Lastly, I have been extremely bloated. Is this normal? Like i look 4 months pregnant already.

And my lower stomach is hard. That’s normal right?
