Hopefully its nothing to worry about, after my first cycle (4 weeks out) my BP was abnormally high like 160/110, then it dropped to 130/80, after i quit smoking it dropped even lower to 120/70. The stress or worries can raise it back up as one of my good friends commited suicide i was so stressed out that it shot back up to 150/100.
Relax, take it easy for a bit and then go in a week check it out, hopefully its nothing to worry about.
