Sore Breast

Samantha
Ok so long story short my IUD was removed in November of last year. It took 41 days for my first period to start. Then it took 31 days for my second period to start. So I fixed my app on my phone to say that my cycles are 30 days. And so I went off that and had sex with my husband 3 of the 6 fertility days. And well I've had sore breast (to the touch and it anything even grazes my breast I almost wanna cry) these last 3 days. Not exactly sure when I ovulated. It said I was fertile 9-14 and we had sex on the 9th, 11th and 14th. My breast started hurting on the 16th. On the app it states I'm suppose to start on the 26th. Do you all think I could be pregnant or is it to early to tell? Any info would be great. I want to be pregnant so bad.
