i had tan spotting only twice. the first time it was 4 weeks and around afternoon and very random, no cramping. although i had cramping throughout the day, normally just mornings and evenings on a daily basis anyway. second time was caused by sexual activity. this spotting occurred tan as well, but it lasted all day but not everytime i wiped. sometimes it would be on my pantiliner though. thats the last time i spotted, two weeks ago. i still continue to get cramping. spotting is absolutely normal after sexual activity but even so, it keeps me from wanting to make love because spotting is just freaking me out no matter what!
i also went to the doctor about my cramping and he claimed that everything is completely normal and baby is fine, and i should continue to feel cramping over the next month as this will be my uterus growing. well its daily and 90% likely to be on the left side in one place. i also get period-like pains, which my midwife told me i should expect(before i even got them)
spotting is common in pregnancy and should only worry about it when its red and heavy like a period or similar. the cramping should only be a concern if its extremely painful or if you double over from it. strangely, my grandma and my sister's daughter both had their period(or bleeding and cramping just like it) for the first few months of their pregnancies. both had healthy happy babies.
