I normally get my period around the 23rd-25th of every month and it has been almost regular, during last month (June) i had unprotected sex after my period and i took Prostinor 2 after which i got my period again at the start of July . During the month of July my and my fiance had unprotected sex twice , during the first time he was sure of not ejaculating inside and i was worried about the continuous use of Prostinor 2 so we didn't take any contraceptives. (which i now understand is an extremely foolish thing to do)

During the second time we did use Prostinor 2. Now i'm late for my period and i've been getting lower abdominal pains after the use of the pill. I haven't been experiencing any fatigueness or cramps or tenderness in breasts. Should i be worried ?
