Cycle day 9 --> cramps?

Sammi • 25yrs old, Mumma of 1 beautiful daughter (3) married for 4yrs & just got my BFP after 1.4yrs TTC #2 ❤️
Hubby and I have BD'd twice this week (supposedly my fertility period this week) and I've woken with cramps this morning... Could this be good news??
​I've also been taking my bbt using a normal thermometer but have just ordered my first bbt thermometer along with my first ovulation tests
​Waiting for them to be delivered - sooo excited!!
