Ch 31 Maetel finally figured out that alexa is pregnant
Ch 39 Maetel finally figured out that he is the father after rescuing alexa from duke wayton(the serial killer). Alexa woke up and found that he was locked up (could be because maetel is afraid that alexa will escape especially after knowing he is the father and that alexa planned to get abortion, albeit still undecided).

Maetel discovers alexa's pregnancy at ch 31.
I read the spanish raws at https://lectormanga.com/library/manhwa/53987/quien-es-el-que-manda using the tap to translate app. Maetel finally connected the various clues and concluded that alexa is pregnant. However, they still do not who the father is (ch 33)

I was kinda scared to read at first because usually the starting point of isekai manhwas like this is after something major happens and fl will be in a major disadvantage, in this case, I thought she'd be transmigrated after original started beating her son. I gained the courage to read after seeing the comments section so positive. Thankfully, my fears didn't come true and she transmigrated before the war occured ╮(⌒▽⌒)╭

Is there a novel to this manhwa???

There is, but it's not being translated right now. You can read spoilers and a few MTL'd scenes on the NovelUpdates Spoiler Thread, though.

Say, did this manhwa regress? I mean, were chapters deleted then reuploaded? I'm not really sure but I think this is the manhwa where:
Paulina marries Frau. The emperor finds dirt on frau and learns he actually has a son. The emperor and paul travel to the village where frau is secretly visiting his son (paul doesn't know the purpose of their trip and about frau's son). She divorces and injures frau (i forgot if they really got married or if they were still in the process). She was sad. Paul and emperor stopped in an inn to stay. They get drunk. They do the deed. They got awkward to returning back to the palace. Paul found out she's pregnant. She resigns from her post. She hides in another property far from the palace to give birth. She was successful in hiding until a few days after giving birth. The emperor sent a close attendant (forgot who) and discovers she bore the emperor's son. I vaguely remember what happened after but i'll skip it coz i'm not really sure. Then, paul became the empress i think (the concubines were released from being concubine long before) but still retains the Marquis title saying she'll pass it to the one who is worthy along with the surname his majesty bestowed upon her coz she can't bear for the name to disappear.
Again, i think this is the manhwa the spoiler belongs to but i'm not 100% sure coz my memory's bad.
Reading this chapter was so annoying.
The reasons:
1. My internet connection is slow.
2. The pictures load very very VERY SLOWLY.
3. It would sometimes stop just at the closeup of the emperor's face.
Can you imagine just how annoying that is?!!
the chapter loaded pretty fast for me, but it could just be me.
HAHA! I used data cuz my WiFi sucks
