Pregnant AGAIN maybe

I just had my baby 7 weeks ago and I haven’t gotten my period yet but yesterday I had like red discharge on my underwear but I keep on checking and nothing gets picked up when I wipe. Could that have been implantation 🙁🙁 i did want my babies close in age but not this close 😐😐 we’ve been have sex since I was 3 weeks pp I couldn’t wait. Instead of been dry and not wanting it, i was extra wet and would want it every day. He came in me 2 times. The first time like week and a half ago. The second time about 3 days ago. Another baby would be a blessing but I feel that we should be more careful. I haven’t told anyone I just needed to get this off my chest. Please no dude comments
