Not TTC, on mini pill, but ovulated. Need advice!

Angel

I haven't had a period since my daughter was a month old back in November. I figured it was either because I'd started Norlyda or breastfeeding or a mix of the two. So, I didn't expect to have EWCM on the 17th and 18th after having sex on my husband's birthday on July 16th or having a positive OPK today when I realized I was having ovulation cramps. I don't know if I should keep taking my birth control and iron pills or if I should stop just in case.
