My girlfriend and I had unprotected twice. One day after her periods stopped (she took a I pill within 48 hours). Then 5 days after her periods stopped we had sex again. I did not give I pill again. 2 days later she had bleeding. More then spotting and less then a normal period and Dark in colour. Then bleeding stopped 2 days later. After 2 day bleeding stopped she had bleeding again 9 days later and this time it lasted 4 days like a normal period. Cramps, blood flow and colour the same as a period. Now it's the 8th again and she has been having cramps in the lower area of her stomach. The cramps are on and off and heavy and also she is having lower pack pain. She has taken clip 500 to regulate her periods. Her normal mens date is 16th of every month. Is she pregnant or what's happening?
