can I get some help please.

So me and my hubby have been ttc but not how you would typically think. I've always had irregular periods so we'd just have sex every other night but no luck. I've never used opk but I decided to use one out of the blue cause I noticed I was having ewcm I used a clear blue Advance April 15th and got a smiley face that stayed So I believe I was about to ovulate so we BD that day and the next. I've been cramping today and have had sore breasts. When should I test since my periods are kinda irregular. Should I test the 30th which will be 14 days since the positive opk? Thanks so much 💗
