The strangest thing I have ever posted...

So, I started af on 9th Feb, I was supposed to start 10th. It lasted for two days max and come to think of it I had no cramping or headaches the week before which I usually get.... fast forward to yesterday (cd9) and my boobs are hurting, so much so that they feel bruised and my stomach is constantly cramping. I had a rubbish sleep last night and I just couldn’t get to sleep. Would I be stupid in taking a pregnancy test even though I’ve had my period? So so strange. Ttc for 14 months with regular on the date periods... 🤷‍♀️ Help would be appreciated or if anyone has experienced the same...
