Possible miscarriage? Help!

Samantha

So last night, my S/O and I were having sex.. well we had to stop because I got such bad cramps to where I was in tears. The cramps came and went all last night and today they are still kinda there and I haven felt my little one kick since yesterday around 3 PM. I’m scared that something seriously happened. What do I do?? Has anyone went through this?
