Hi mama's... can you feel preg symptoms right after ovulation? I am on day 15-16 and have had headaches and nausea for the last two days .. never felt like this before so not sure what to think of it? Trying for second baby and don't remember feeling like this before on the first baby. Please let me know what to make of this? Thanks.
