So I'm still a little ways from my period- I used to use a different app which said I was gonna start my period on June 12. When I started using glow and TTC I was using OPKs which told me I ovulated later than expected fertile window. We had lots of sex and the last few days I've been nauseous on and off but this morning I woke up with terrible nausea. I was dry heaving, it was terrible. I didn't think I'd be able to eat but I ate a little not really hungry. Glow says my period is to start in 8 days... is this too early to be getting these feelings? My boobs are sore which is sometimes a pms symptom for me I've had a little mild cramping but nothing really to mention.
