Please help!! BFP OPK pregnant??

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​I have irregular periods so I have no idea where I am in my cycle. I haven't had a period in a little over a month. For the past few days my breasts have been extremely sore, especially my nipples, which never happens even during PMS. I read that OPKs can sometimes detect pregnancy so I took one and immediately got a BFP. I took another right after and got another positive. Even darker than the control line. Has anyone experienced this or am I just ovulating? Please help!!
