Unfortunately we will not know unless we get the genetic screening or wait for the anatomy scan in the second trimester. Every pregnancy can be different even if you are carrying a baby of the same sex as your first.
There is no way to predict the gender,based on day of intercourse or the symptoms.yes you tube is full of such hypothesis,but they are seldom facts.the only way is by USG,but at many places gender diagnosis is a punishable offence..so pray for a healthy baby and leave the rest to god.if you are worried ,ask your sonologist at 16weeks scan.
With my girl pregnancies I was horribly sick, with my son I wasn't anything but a little nauseous here and there! My pregnancy now I exactly like my sons! So I'm going with a boy now again lol if you are anything like me, I would guess you are having a girl again! But you never know!
