I have a question!

Casi • I have been trying to conceive for a few months. Wish me luck!
My husband and I have just recently started to ttc this month. I think he has super sperm, and I know I'm extremely fertile. Thankfully, I am blessed I have never had trouble in conceiving. I have a question.... we had sex on 2 very highly fertile days of mine. That was a week ago. I'm already experiencing pregnant-like symptoms: back ache, cramps, extremely moody.... now I'm extremely gassy. One, is it too early for signs to start appearing for me? And two... I know being gassy during pregnancy is common, but could it also be a early pregnancy sign? Good luck and God bless to all ttc!
