I have been diagnosed with mild endrometrsois this month and im only 20 years old. Me and my long term partner are ttc we had unprotected last night and the doctor said im ovulation from the 19 onwards. if i am pregnant i am due my periods the 2nd of August would i miss my periods then or would it be the next time. also i have a congested bladder would that effect the baby if were pregnant. thanks for you time and answers xox :)
