Life ....

Got multiple BFP tests Sunday ... made my appts Monday ... was ecstatic !!! Wends woke up to bleeding , at 5 wks my HCG level was 97 ... they told me to come back Monday ... it’s got worst today and I honestly know deep down I am having a miscarriage (I am heading to the ER soon as my doctor said if it worsens to go) my question is after miscarriage how many people immediately try again and successfully succeed ? I have heard that you are really fertile after a miscarriage and with only being 5 weeks I feel like physically my body will be ok (emotionally I am a wreck but I am staying positive) also with his miscarriage when/if I conceive again will they immediately rest my levels and keep a watch on me ? Thanks for any input ladies
