Preg symptoms/or menstrual

I'm a mom to 5 and had to miscarriages te last 2 years.  Using pull out method. My menstrual symptoms vary from month to month. Sometimes I spot before, sometimes my breast are sore. Sometimes I have cramps before.   So period is due in 2 days. Cervix is very high can barely reach but it's firm and closed. Breasts have been sore for several days now since Monday and it's Thursday. No spotting, cramping, some nauseousness in the morning but it goes away and I'm peeing like a racehorse. Also not a lot of cervical mucous. Any insight ??
