Ok so I just found out I’m finally getting our long awaited rainbow baby on November 6th so I’m like verrrrry early in my pregnancy like 3 weeks and 6 days but I’m having random bouts of cramping. Nothing to bad it’s just every now and then I’ll get a kind of straining pain jolt through my pelvis or I’ll have 2 or 3 minutes of a little bit of cramping but since we’ve already lost 4 baby’s since April 2018 I’m horrified any time I feel any pain because it scares me I’m loosing another one. This will be baby #2 if it makes it but my daughter is 5 years old now so I can’t remember if I ever felt this while I was pregnant with her or not please anyone that can tell me this is normal I’d reallllllly appreciate it. Btw I have no bleeding at all just random cramping and pains at times and never for a long time
