7+5 questions..

Hello ladies! So I am 7 weeks and 5 days today and I’ve been having light cramps which I’m told is normal. Well me and my boyfriend was making love earlier and after I got off it kinda starting hurting like sharp pains. So I stopped. I’m noticing my belly feels like I have 80 pounds of extra on it so it’s super super heavy. Which is weird. Also I am SOOOO gassy. Why 😭 this is my second child and my first was nothing like this. I’m not spotting at all and I feel like I’ve gain 30 pounds already.
