Severe cramps after sex?

Lindsey

y'all what the friggin heck. I got my bfp this past Monday, and should be 4.5 weeks with a slight possibility of conceiving last month which would be 8.5 weeks. this would be my first! BD with the hubs last night and immediately after I had severe cramps that put me in tears. I ran to the bathroom bc I was scared I was gonna be bleeding everywhere or something but I was in so much pain. AND!! I didn't even orgasm so I don't get it. anyone else?? or anyone that can put me at ease? I have my first appointment March 21
