Missed Period & Negative Test

[Katie00001]

Hi everyone,

I’ve missed my period by around a week or two now..( it’s usually consistent. Same time every month ) I’ve done 2 urine tests and had a blood test at the doctors, all of which are negative for pregnancy. I’m having pains in my stomach and others signs of pregnancy ....

Obviously there’s still no chance of being pregnant ?

How do I work out my ovulation days now that I haven’t had a period ?

Thanks in advance :))

Currently in the same position. All urine test are negative but haven't taken blood test yet.
