Any ladies who can relate ???

I have irregular periods. I would go months without period. Now that we are tryna start a family it’s been hard tracking ovulation and stuff. Last period was March 10. Couple weeks after my period I started having lower back pain I tested to see if I was ovulating or not. Turns out I was. I ovulated April 5. The past two days I’ve been having lower abdomen pain and lower back pain . Which are really painful I’m scared to take a test and to find out it’s negative. I really don’t think it’s my period since I have irregular period. Could it be implantation symptoms??? Haven’t spotted or anything yet .
