we're trying to conceive (all advice needed)

Jessica
So me and my fiancé had sex on the highest peek days . And even last Friday. On Monday early morning I had spotting. I figured it was from the amount of alcohol I drank the night before. But I've been having mild cramping, something like pulling behind my belly button one day and pressure like cramps with back pain out of this world. Most of the time I cramp it feels like I have to go poop so I've been like it's just gas. But me having gas so often is starting to raise question. My period isn't due until the first week of October and I'm so anxious to find out if I'm bugging or if I've experience implantation and ya girl might be expecting... someone help!! I hate I don't know these things lol
