Period CD 20

I havent posted before but follow others. I have been TTC for 9 minths now. I have had atleast 1 chemical in April and I think I had one last moth but doc said it wasnt. I started my period on day 20 this month after day 32 last. I am on day 5 of my leriod today and I am cramping and have sore breasts. I was also teally nauseous yesterday. I am not sure what all of this means. I have also been doing acupuncture to tey and regulate cycle. I dont want to go to doc again over nothing but I am 34 (almost 35) and getting extremely frustrated. 

I guess what I am asking is if anyone else had an extremely weird cycle after a chemical? or bled the first month of their pregnancy?
