Hello. I'm on a 33 day cycle. Last period 4 to 10 march. Period late by 5 days now. Supposed to come either 5 or 6 april. I could have ovulated on 23 march. From 29 march till now, I've been having very mild but consistent cramping lower pelvis (taking turns on right and left side) and lower right back (lower right back has been quite a killer) and I've never experienced this before throughout my periods. My temperature has been on the higher side since ovulation and has not decreased. My always-sore/full/heavy breasts a few days before period is now gone. My breasts are not sore or heavy or full at all for this month's due period. But I've been having headaches, slight dizziness (these are quite common for me due period), breathlessness and fatigue (these two are not at all common when due period) when walking a distance or doing some Chores. My tests have been negative since 10 dpo. I'm now 18 dpo. So is my period just late OR could i have ovulated and implanted late and be pregnant?
