Had period-like blood for two days at my mid-cycle point (heaviest mid cycle spotting I ever had, tho some is normal for me), a clear BBT shift but lower than normal, and little to no typical PMS symptoms (breasts and tummy are very slightly bloated but no pain). Had sex about 8 days before my peak day. Now I'm on day 34 (usually a 28-32 day cycle). What gives? Maybe I should take a test.
