Needing more advice

OK I posted yesterday and feel dumb posted again today. I just have questions. Sorry if TMI, hubby and I have been ttc real hard since last month. So my question is my most fertile day was 23rd and hubby and ibhad sex, and every night since, it's too early to test my period is supposed to be here around the 8th of Oct according to glow, well I've been having sore breasts, nipples, and basic she brests including sides, nausea, cramping, and last night started feeling light pressure around lower tummy and ovary area, and also experiencing pressure and little pain on left side. What's going on and opinions and advice very welcome. Thanks in advance and baby dust to all. If my other post showed up, I apologize because I wasn't sure if it posted or not.
