Stressed and depressed

Hiedi

I miscarried June 13 I was 6 weeks along ... the doctor did blood work a week later and my HCG was 0 .... my period came on July 15 lasted 7 days ... so according to my chart I should of Ovulated on the 29th so I felt like I ovulated before then... I didn’t take any tests to check .... so that brings me to the last few days... My boobs have hurt so so bad I spotted just a very small amount two days ago... but I never really had any CM since my period or it’s just been watery not egg whites like... has anyone else had issues with ovulation being off since their miscarriage? I’m planning on getting tests strips and want to know what kind do you guys recommend
