10dp5dt Cramping

Hi all! I had my first fresh transfer on 2/24, and my beta isn’t until 3/9 (my clinic makes you wait 14 days..ugh!). My question is I have been having AF type cramping since 8dp5dt and starting to get nervous it’s my period coming. They come and go and sometimes I get a very sharp pain that lasts about a minute and then goes back to more a period dull cramp... just wondering if anyone had something similar and had success?

FYI - after so many negative hpt, I am not going to test at home

Thank you!

Update - positive beta!! 1426 HCG
