I had a 2 days period on the 30th september after taking contraceptive pills for only one month. was expecting to have my period on the 30th of october so I had unprotected sex 2 days before. My period is 4 days late now. I have a 14 months baby already, possible little brother or sister for him on the way??? God help!!! (I am on metotrexate and humira) Sooo scared.
