Confused and need help

Ashley • Trying to conceive my first child 👶🏾 before am 30

My last period was feb 27th my cycles are 27/28 and ALWAYS on time maybe a day early or a day late. Right before feb cycle I had my yearly physical done and 3 weeks ago my result came back everything good and normal. Although glo said was to ovulate on the 14/15 I had no symptoms like I normally would...egg white cm ovary pain that’s normal for me. Around the 18-22 of March my breast were beyond sore for no reason I didn’t think about ovulation at all because the time has passed. Me and SO bd on the 23rd and period was due 27/28 so I taught I was safe. Idk if I ovulated late this month but my period is 2 weeks late the first week I tested and all bfn this week I didn’t bother I will just go to the doctors on Thursday. Symptoms I am having now sore breasts extreme exhaustion lightheaded headaches mild cramping bloating.

P.S am not stressed or on no type of medications nor has my life changed in anyway.
