Sore boobs again....

So AF is supposed to come in 6 days. I took a test and got a BFN today. My boobs are sore my appetite has been a rollercoaster and my husband and I have been trying to conceive since our miscarriage June of 2017. This makes the second time my boobs have hurt like this but the first time I got a BFN as well. Any advice? Oh I take prenatal vitamins and we've tried Preseed a few times and still nothing....

Edit... My husband and I just got married Jan. 5th and my peak day was the 5th but my actual ovulation day was the 6th. Was I supposed to have sex on the 5th or 6th?
