Helppp.

Hi ladies, so I have a 28 day regular cycle, however i’ve always ovulated in cycle day 20. I had a D&C feb 14 and already had my first cycle since i’m now on day 13. as far as I know I haven’t ovulated yet but i’ve been having mild cramping it’s almost like it’s wrapping around towards my back to and i have a little nausea. i feel like it would be a waste to take a test. Me and my fiancé have sex every single day which I know sounds crazy but that’s just us 😂🤷🏼‍♀️. can anyone help? or have the same experience?
