Weird bleeding vs. chicken!

Jessica
So last week I had some bleeding, went to out of hours and Dr said it's probably a miscarriage but ring midwife to send you for a scan. Rang midwife and she said it's probably due to having sex the night before, so she didn't book a scan. So 6 days later I've started bleeding again, feel faint and nauseous, and a few mild cramps. But haven't had sex since last week because it made me bleed. I feel too silly ringing the midwife, I'm only 7 weeks and don't want want anybody thinking I'm an idiot because it's so early.. Should I just hold it out and test in a week or contact midwife?
