Ok so ladies my fiancé and I bd on 6-16-18 and I track my ovulation through a calendar I keep. And it’s now 6-29-18 and my boobs hurt like crazy, they feel bigger and I am eating like crazy!!!! My period is due tomorrow but I’m having no menstrual symptoms, I normally do I would get cramps a day before my period. My daughters birthday is today and idk if I should test today or tomorrow? Please help? And what’s the best brand? My daughter has been asking for a brother or sister.
