I need opinions please.

Hey guys! So my boyfriend and I had sex on the 7th of April and my period started 2 days later. At that point I had stopped my birth control for a month already after being on it 6 months (on and off honestly). My boyfriend and I are just kinda in the "if god wants us to be parents then we will be" so I stopped them. Anywho! 2 weeks after being off my period I had one day of brown spotting, it was so little that I didn't even go through one panty liner. Since then I've had some small dull aches, some sharp but nothing like a period cramp (my period isn't due for another 13 days). I have noticed I've been peeing a lot more, but I'm not sure if it's because I've been drinking more water recently. Also, craving pickles big time, even drank a whole jar of juice tonight LOL. So question is, has anyone ever got pregnant right before their period? And how soon could I take a PT? The spotting happened 5 days ago.
