So confused! Tmi personal info

So my last normal cycle was on June 18th it came a week early but sometimes it does that my husband and I started ttc right after that and I never got my af in July well on August 8 I got my af which was heavy the first day and light the following 3 days normal length but usually stays in the heavyish area of flow well I so far have no signs of af and I have gained nearly 10 pounds since June! I am going to schedule an appointment with my midwife tomorrow but he is booked out a week in advance. Does anyone have any clue as what might be going on? The only other symptoms that could be attributed to pregnancy other then the weight gain is really really sore breast for almost two full weeks now and a really bloated belly.
