Recently I had period but it was bit unusual as compared to the previous. The flow had some black spots as well its was dark brown too. My flow got stopped on the fourth day. I had sex with my boyfriend bfre one and half month and I had periods last month too after that. We used condoms while having sex. Evry symptoms were same as usual but this blackspot and dark brown colour worries me. It would very kind if you give me advice.
