Your body chemistry is still out of wack, the medical doctors do not fix problems they banage the symptoms. You can always speak to an herbalist, Try an herb Vitex berry/Chaste tree.

Since you were pregnant not to long ago, it does take a little while for your body to get back it to normal flow. I am in nursing school and my teacher has told us that you have to ovulate first before you can have a period. Maybe your hormone levels were up a little bit in march, but to the best of my knowledge you cannot have a period unless you have ovulated. Hope this helps.
OPKs are not entirely reliable. They simply tell you whether or not you have a rise in LH but does not guarantee that you have ovulated.
Give your body a few months to work itself out - your hormones are probably slightly out of balance.
