So I didn't get my period last month last period was July 19th to 23rd. Just went to my Gyno and asked if it's normal to miss period for a month and she said yes due to the type of birth control. But last week I started to get cramps but no period with bloating and my boob and nipples hurt like crazy. Me and my boyfriend had sex with no protection( also with no birth control) on august 24th. I haven't took a test yet wanted to wait a week or so just in case I test to soon. I'm picking up test maybe today or tomorrow. But my question is are these some signs of being pregnant? And how soon can you feel symptoms? Please help. Thank you!
