Does this sound crazy? Early pregnancy symptoms.

I don't actually know when I ovulated as I haven't had a normal period since finishing my contraceptive pill near the end of May (have been on the pill too long to remember my cycle) and I've had a withdrawal bleed that ended 1st June, but that's it... I've been tracking CM for about a week or so.

*4 days ago, I had globby, jelly like, very stretchy EWCM. So DH and I DTD.

*The next day, I had this rush of fatigue come over me whilst sitting on the couch. Labia aches started during the day like AF was on her way.

*Day after that, extremely tired, cramps similar to gas, not far above my vagina. Still labia aches. Shooting pain on left and right sides. Very bloated and gassy. I have noted that normal bloating for me occurs from my upper stomach down to below my belly button, but this is only below it this time. CM getting creamy and sticky.

*Today, cramps continued but more painful, localised shooting pain on right side, pull between belly button and vagina for a few seconds. CM is creamy, watery, some small stickiness.

Does this not sound like early pregnancy symptoms? Or am I clutching at straws? And when should I test?
