Heart Rate

I have no clue when I ovulated hubby and I have been BD every other day this entire month! Yesterday I noticed some pinkish brownish spotting with a white thick discharge (kinda like rotten milk minus the smell) no odor. Then today I have noticed a increase in heart rate. My heart rate is generally at 70-75 and today my resting is 90-95. Did anyone notice a heart rate change after conception/implantion?
