Кровянистые выделения на 5 неделе беременности: у кого так было и все хорошо?

Well after 4 positive pregnancy tests, and so far on day 2 of bleeding…not sure what to expect. I should be 5 weeks pregnant. Went to the OB today and did a blood test and have to go back Thursday and do another one to check hcg levels and make sure they are increasing…. Has anyone went through this and the baby been fine? Losing my mind a little…
