fluctuating blood pressure before my cycle

I am confused and would like your input, when I developed Lyme Disease I also got Diabetes and high blood pressure, my diabetes is perfectly under control, my blood pressure is very hard to manage, it seems like it goes high a few days before my period and gets better as soon as I start bleeding and is back to normal after day 2, do you think this is caused by Lyme Disease or by some hormonal issue.

( I am off meds for about 1 1/2 years, was treated for about 1 1/2 years with different combinations of antibiotics and got better)

It's funny I saw this today.  My LLMD put me on Cozaar (50mg) last month - bp was out of sight (has always been fine before Lyme) and seems to get worse around this time of the month (24-30) during the "spirochete reproductive cycle" (I don't have periods - had hysterectomy at 23 years of age).  She told me to give 50mg a month, if little or no improvement, we'll try 100mg, if that doesn't work, we'll try another drug.  I also now have to take atenelol for tachycardia (never had it before Lyme either).  Anyway, my BP last night was 163/110.  Called LLMD today - she's bumping me to 100mg.  I'm hoping it helps.  The atenelol works great - heart rate used to be 100-120, now down in 60s-70s.  So I'm wondering if your spirochete reproductive cycle coincides with your period?  Just a thought.
