before you get your first period back, you will ovulate for that first cycle. that ovulation takes place about 10-14 days before that first period, and that is when you can get pregnant. that is why people say you can get pregnant without getting your period,... you ARE getting your period at that time, it just hasnt gotten to that point in the cycle yet, know what i mean? you might feel yourself ovulate, even if you never did before you were pregnant, as your body is different now (no kidding, right? :)) it feels like cramping on one side, and you will probably have what they call egg-white cervical mucus. that is your prime time to concieve. if your baby is 7 mos, he/she? is probably eating a lot more solids? or will be soon? that may decrease your breastfeeding enough to get your period back. it may not. all my babies were exlusively breastfed to 6 or 7 mos, started solids very slowly, and i got my period back at 13 mos with my first, then stopped breastfeeding at 18 mos and got pregnant about 10 minutes later. i got my period back at 9 mos with my second, got pregnant at about 13 mos and my doc told me to wean her off the breast, so i did it by 15 mos. and i got my period back at 15 mos with my 3rd, still breastfeeding... so, all were different, but i got my period back while still breastfeeding with all 3. best of luck, D.
